Question

Which is an equation in point-slope form of the line that passes through the points ( -4, -1) and (5, 7) ? Please help me

Answer 1

y = mx + b

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

solve for m and then use any of these two points to figure out b.

Answer 2

The options are A. Y+4=9/8 (x+1).
B. Y+1=8/9 (x+4)
C. Y+1=8/7 (x+4)
D. Y-1=8/9 (x-4)
