Question

What is the equation in point-slope form of a line that passes through the points and (5, 7) and (4 – 1)

A) y + 1 = 8/7 (x + 4)
B) y - 1= 8/9 (x – 4)
C) y +1 = 8/9 (x + 4)
D) y + 4 = 9/8(x + 1)

Answer 1

y-7=8(x-5)

Explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(-1-7)/(4-5)

m=-8/-1

m=8/1

m=8

y-7=8(x-5)
