Answer:
See below:
Step-by-step explanation:
Hello! I hope you are having a nice day.
We can solve this equation in a single step, we just need a bit of theory and a graph.
We can first see that its in [tex]y=mx+b[/tex] form. Which is also known as Slope-Intercept form.
This means that we know the following.
[tex]b[/tex] is the y coordinate of the y intercept.[tex]m[/tex] is the slope of the line.Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).
Now that we've gotten that, we can start graphing.
The y intercept is -7 so we can plot (0,-7) as one of our points.
The slope of 3 means that we got up 3 units then right a single unit.
Therefore, another point could be (1,-4).
With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.
Cheers!
Answer:
Step-by-step explanation:
y = 3x - 7 is a linear equation with y-intercept -7 (or (0, -7) ) and slope 3. These two quantities are instantly readable from the equation.
There are several ways in which we may graph this equation. One is to plot the y-intercept (0, -7) Then choose an x-value, such as 3, and evaluate the function at that x value. We see that y = 9 - 7, or y = 2, when x = 3. Then another point on the graph besides (0, -7) is (3, 2). Plot (3, 2) and then draw a line through the two plotted points.
Here's another way:
The slope here is 3, or 3/1, which represents rise / run. Plot (0, -7) as before.
Move your pencil from (0, -7) 1 space to the right and 7 spaces up. Then plot a new point at that location. Draw a line through (0, -7) and (1, 0).

Answer:
C) 2.6
Work Shown:
a = x, b = 3, c = 4
a^2 + b^2 = c^2 ... pythagorean theorem
x^2 + (3)^2 = (4)^2
x^2 + 9 = 16
x^2 = 16 - 9
x^2 = 7
x = sqrt(7)
x = 2.64575131106459

Y = 4x + 9
What is the slope and the y-intercept?
Answers
Answer:
y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9
Answer:
m = 4b = 9Step-by-step explanation:
We know that:
y = mx + by = 4x + 9If we compare these two equations, we can find the slope and the y-intercept.
=> (y = mx + b) = (y = 4x + 9)
We can clearly see that 'm = 4' and 'b = 9'.
Conclusion:
Therefore:
m = 4b = 9Hoped this helped.
