Question

which ordered pair is a solution of the equation y=-5x+4?
(2,14)
(5,-29)
(3,-19)
(5,-21)

Answer 1

(2, 14)

14 = - 5(2) + 4
15 = -10 + 4
15 = -6 not a solution..

(5, - 29)

- 29 = - 5(5) + 4
- 29 = - 25 + 4
- 29 = - 21 not a solution

(3, - 19)

- 19 = - 5(3) + 4
- 19 = - 15 + 4
- 19 = - 11 not a solution

(5, - 21)

- 21 = - 5(5) + 4
- 21 = - 25 + 4
- 21 = - 21 < ----- is the solution of the equation
