Answer:

(b) y -5 = 3/4(x -6)

Explanation:

The point-slope form of the equation for a line with slope m through point (h, k) is ...

y -k = m(x -h)

Your graph has two points marked: (-2, -1) and (6, 5). Even if you don't know the slope, these tell you the form of the equation will be ...

y +1 = m(x +2) . . . . no match

y -5 = m(x -6) . . . . matches choice B

__

If you like, you can figure out the slope to be ...

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

m = (5 -(-1))/(6 -(-2)) = 6/8 = 3/4

All the answer choices agree that this is the slope of the line.
