Question

Write each line in slope-intercept form. Then

Answer 1

Answer:

equation: y = -4x + 7

slope: -4

y-intercept: 7

Step-by-step explanation:

in order to make this equation into slope-intercept form, you have to isolate the y

to do that, you can subtract the 4x on both sides, which will leave y by itself

4x + y = 7

-4x        -4x

y = -4x + 7

the slope is -4

and the y-intercept is 7

Answer 2

Answer:

   Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

   Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
