Question

A line goes through the point (5,7) and has a slope m= -3

Answer 1

y = -3x + 22

plug in the given point and the slope into point slope form:
y-7 = -3 (x-5)

solve for y to get slope intercept form
y-7 = -3x + 15
y = -3x + 22

Answer 2

y=-3x+7

Explanation:

The slope form is y=mx+b

7 replaces B since the points intercept at positive 7. The slope is already given to you so that ur equations
