Write an equation in slope intercept form for this line

Question

A line passes through the point (- 7 ,4 ) and has a slope of -3

Answer 1

y = -3x +b is slope intercept form, y=mx+b where m=slope and b=y intercept

plug in the point to find b

4 = -3(-7) + b

4 = 21 +b

b = 4 -21 =-17

y = -3x -17 is the line with slope -3 through the point (-7,4), in slope intercept form
