Sagot :

Answer:

y = ½x + (-2)

Step-by-step explanation:

step 1. find the slope (m) of the 1st line

the slope is the coefficient of x

m1 = -2

step 2. if both line were perpendicular, so

m1 x m2 = -1

-2 x m2 = -1

m2 = ½

step 3. Arrange 2nd line equation with "(y-y2) = m2(x - x2)

(x2, y2) = (8,2)

y - 2 = ½ (x - 8)

y - 2 = ½x - 4 + 2

y = ½x - 2
