Which of the point-slope equations below are correct for the line that passes through points (-4,-14) and (1,3)?


Check ALL that apply.

Ay-3=7/5(x-1)

By+4=7/5(x-4)

Cy+4=5/7(x+4)

Dy+4=7/5(x+4)

Ey-(-4)=7/5(x-(-4))

F. y-3=7/5(x+1)

(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5

y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one

y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one
