Question

Reasoning with Equations

Answer 1

find the slope
(1/2, 3) x1 = 1/2 and y1 = 3
(-4,-1) x2 = -4 and y2 = -1
slope(m) = (y2 - y1) / (x2 - x1)
now we sub
slope(m) = (-1-3) / (-4-1/2)
slope(m) = -4/(-8/2 - 1/2)
slope(m) = -4/(-9/2)
slope(m) = -4 * -2/9
slope(m) = 8/9

point slope form : y - y1 = m(x - x1)
(-4,-1) x1 = -4 and y1 = -1
slope(m) = 8/9
now we sub
y - (-1) = 8/9(x - (-4)
y + 1 = 8/9(x + 4)

any questions ?
