Question

Which answer is an equation in point-slope form for the given point and slope?
point: (-4,1); slope: 7

A. y+1=7 (3+4)

B. y+1=7(2 - 4)

C. y-1=7(x+4)

D. y-1=7 (x – 4)

Answer 1

Answer:

y - 1 = 7(x + 4)     (Answer C)

Step-by-step explanation:

Learn (or recall) the point-slope form y - k = m(x - h).

Substitute the givens m = 7 and point:  (-4, 1) into this framework (form):

y - 1 = (7)(x + 4), or y - 1 = 7(x + 4)  (Answer C)
