Answer:
- See below
Step-by-step explanation:
<u>Find the slope of each line:</u>
- m(AB) = (3 - 1)/(- 1 - 4) = 2 / - 5 = - 2/5
- m(GD) = (3 + 2)/(6 - 4) = 5/2
<u>The product of the slopes is - 1, hence the lines are perpendicular:</u>
- - 2/5 * 5/2 = - 1
Equation of each line
<u>Line AB</u>
- y - 1 = -2/5(x - 4) ⇒ y = - 2/5x + 8/5 + 1 ⇒ y = - 2/5x + 13/5
<u>line GD</u>
- y + 2 = 5/2(x - 4) ⇒ y = 5/2x - 10 - 2 ⇒ y = 5/2x - 12
