A line has a slope of 3 and passes through the point (4, 7). What is its equation in
slope-intercept form?
Answer:
Step-by-step explanation:
y - 7 = 3(x - 4)
y - 7 = 3x - 12
y = 3x - 5
The equation of the line in slope intercept form having slope 3 and passing through the point (4, 7) is y = 3x - 5.
What is Slope?Slope of a line is the rise over the run of the given line. It is usually denoted by m.
In other words, Slope of a line can be calculated by finding the difference of the y coordinates divided by the difference of the x coordinates where x coordinate and y coordinate of two points are given.
Equation of a line in slope intercept form is given by
y = mx + c
where, m is the slope and c is the y- intercept.
Now y-intercept is the y-coordinate of the point where x = 0 or when the line touches the Y axis.
Here, m = 3
We have a point (x, y) = (4, 7)
Substituting these values in the equation,
7 = (3 × 4) + c
7 = 12 + c
c = 7 - 12
c = -5
Substituting m = 3 and c = -5,
y = 3x - 5
Hence, the equation of the line passing through the point (4, 7) and with a slope of 3 is y = 3x - 5.

In the third figure for a single input, there is two output thus it will not function thus, l Yes, II Yes, and III No.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
A relation will be a function if for every single x there must be a single y.
As per the given graphs,
In the first and second graphs, for every x value the y has a single value thus it will be a function.
In the third graph, for x there are two y for example at x = -6,(y = 1.4 and y = -6.4 approx) thus it will not be a function.
Hence "In the third figure for a single input, there is two output thus it will not function thus, l Yes, II Yes, and III No".

On a coordinate grid, where is the center of this circle?
x² + y² = 2
A)
(-1, -1)
B)
(0,0)
(1.1)
D)
(2, 2)
Answer:
Option B) (0,0) is the correct answer.
Step-by-step explanation:
Given equation of circle is:
[tex]x^2+y^2 = 2[/tex]
The general form of equation of circle with center at (h,k) and radius r is given by:
[tex](x-h)^2+(y-k)^2 = r^2[/tex]
The given equation of circle can also be written as:
[tex](x-0)^2+(y-0)^2 = 2[/tex]
Comparing it with the general form of equation, we get
h = 0 , k = 0
So the center is (0,0)
Hence,
Option B) (0,0) is the correct answer.

If Mis a centroid of triangle WOR and WM = 16, what is WX?
8
24
10
32
Answer:
WX = 24
Step-by-step explanation:
Centroid of a triangle divides the medians of the triangle in the ratio 2 : 1
Therefore,
WM/ MX = 2/1
16/MX = 2/1
2MX = 16
MX = 16/2
MX = 8
WX = WM + MX
WX = 16 + 8
WX = 24
The value of the side WX is equal to 24. The correct option is B.
What is the centroid of the triangle?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together.
A line connecting a side's midpoint and the triangle's opposite vertex is called the median. Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
The centroid of a triangle divides the medians of the triangle in the ratio of 2: 1.
Here, the ratio of the two sides will be given as:-
WM/ MX = 2/1
Calculate the value of MX to get the value of WX.
16/MX = 2/1
2MX = 16
MX = 16/2
MX = 8
The value of WX will be:-
WX = WM + MX
WX = 16 + 8
WX = 24
Therefore, the value of the side WX is equal to 24.

Step-by-step explanation:
Its pretty simple
The equation that relates the distance (y) and the time (x) is → y = 15x.
What is the general equation of a Straight line?The general equation of a straight line is -
y = mx + c
where -
m is slope of line
c is the y - intercept
Given is a graph that shows a proportional relationship between the number of miles and the number of hours Marco bikes.
First we will find the slope of the straight line. Take two set of coordinates from the graph. We will take → (1, 15) and (2, 30).
The slope of the line can be calculated using the formula -
m = (y₂ - y₁)/(x₂ - x₁)
m =(30 - 15)(2 - 1)
m = 15
The line passes through the origin so its y - intercept (c) will be zero. So, we can write the equation as → y = 15x.
Therefore, the equation that relates the distance (y) and the time (x) is → y = 15x.

Answer:
y = 3x+4.5
Step-by-step explanation:
how can I find the slope to this I need help
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1

How do you find the value of x please help me( Look at the picture provived)
Answer:
x=5
Step-by-step explanation:
We know that a pentagon is in total 540 degrees. From this, we add all other numbers and set them equal to 540 to solve for x.
So, after adding all the angles and setting them equal to 540, we get this.
21x+435=540
21x=105
x= 5
If you want, plug 5 into x and see if it adds up to 540 to check
21(5)+435=540
