Answer:
F. y = .25x + 3
Explanation:
use the slope equation m = y2-y1/x2-x1 with the points. so for this problem it would look like: m = 6-2/12-(-4) which is 1/4 (.25).
For the y-intercept plug what you already know (slope and a set of points) into the slope-intercept formula: 2 = .25(-4) + b and solve.
2 = -1 +b
+1 ( add the one)
b = 3 and that's the y-intercept
