Answer 1

Explanation:

Plugin x and y value in the equation. If both sides are equal, then the points lie on the line,

1) (9 , 3)

y - 3 = 5(x -9) ; x = 9 & y = 3

3 - 3 = 5 *(9 - 9)

0 = 5*0

0 = 0

(9, 3) lies on the described line.

2) (3 , 9) ; x =3 & y = 9

9 - 3 = 5( 3 - 9)

6 = 5*(-6)

6 ≠ -30

(3 , 9) does not lies on the described line.

3) (-9, -3) ; x = -9 & y = -3

-3 - 3 = 5(-9 - 9)

- 6 = 5 * (-18)

-6 ≠ -90

(-9 , -3) does not lies on the described line.

4) (-3, -9)

-9 - 3 = 5 (-3 - 9)

-12 = 5*(-12)

-12 ≠ -60

(-3 , -9) does not lies on the described line.
