Question

Write the equation that describes each line in slope-intercept form.

slope = -3 (-3,4) is on the line

Answer 1

y = -3x - 5

Explanation:

If you substitute -3 from (-3,4) into x in the equation above you would get 4 giving you the point (-3,4).

Answer 2

y=-3x -5

Explanation:

y=mx+b

first -3 = m

so y=-3x+b

then we fill in the blanks for y and x

so 4=-3(-3) +b

use pemdas

-3 x -3 = 9

4=9+b

seperate b

4-9=9+b-9

-5=b so

y=-3m-5
