which ordered pair is a solution of the equation?\ny = -2x + 5\nchoose 1 answer:\na only (2, -9)\nb only (-2, 9)\nc both (2, -9) and (-2, 9)\nd neither

which ordered pair is a solution of the equation?\ny = -2x + 5\nchoose 1 answer:\na only (2, -9)\nb only (-2, 9)\nc both (2, -9) and (-2, 9)\nd neither

Answer

Explanation:

Step1: Test the point (2, - 9)

Substitute (x = 2) and (y=-9) into (y=-2x + 5). (y=-2x + 5) becomes (-9=-2\times2 + 5). Calculate the right - hand side: (-2\times2+5=-4 + 5=1). Since (-9\neq1), ((2,-9)) is not a solution.

Step2: Test the point (-2, 9)

Substitute (x=-2) and (y = 9) into (y=-2x + 5). (y=-2x + 5) becomes (9=-2\times(-2)+5). Calculate the right - hand side: (-2\times(-2)+5=4 + 5=9). Since (9 = 9), ((-2,9)) is a solution.

Answer:

B. Only ((-2,9))
