Question

broke found the equation of the line passing through the points (-7, 25) and (-4, 13) in slope-interceot form as follows.

Answer 1

slope = (25 - 13)/(-7 + 4) = 12/-3 = -4
passing through the points (-7, 25) and (-4, 13)
y = mx+ b
13 = -4(-4) + b
b = 13 - 16
b = -3

equation
y = -4x - 3

hope it helps

Answer 2

The answer is D. She mixed up the slope and y-intercept when she wrote the equation in step 3.

I took the quiz and got it correct. Hope this helps
