Question 8(Multiple Choice Worth 1 points) (08.02 MC) Which graph best represents the solution to the following pair of equations? y = −2x + 13 y = 2x − 3

Answer 1

(4,5)

Explanation:

Answer 2

y = −2x + 13
y = 2x − 3

−2x + 13 = 2x − 3
subtract 2x on both sides
−2x + 13 −2x = 2x − 3 - 2x
simplify
-4x + 13 = -3
subtract 13 on both sides
-4x + 13 -13 = -3 - 13
simplify
-4x = -16
divide both sides by (-4)
x = 4

substitute x = 4 into y = 2x − 3 to find y

y = 2x − 3
y = 2(4)− 3
y = 8 - 3
y = 3

answer
solution x = 4 and y = 3

hope it helps
