Answer:

(8, 3 ) and (- 7, - 2 )

Explanation:

substitute the y- coordinate of the first point into the equation and solve for x.

x - 3(3) = - 1

x - 9 = - 1 ( add 9 to both sides )

x = 8

the first ordered pair is (8, 3 )

substitute the x- coordinate of the second point into the equation and solve for y.

- 7 - 3y = - 1 ( add 7 to both sides )

- 3y = 6 ( divide both sides by - 3 )

y = - 2

the second ordered pair is (- 7, - 2 )
