Answer:
(- 2, 16 )
Explanation:
y = 8x + 32 → (1)
y = - 8x → (2)
substitute y = 8x + 32 into (2)
8x + 32 = - 8x ( add 8x to both sides )
16x + 32 = 0 ( subtract 32 from both sides )
16x = - 32 ( divide both sides by 16 )
x = - 2
substitute x = - 2 into either of the 2 equations and evaluate for y
substituting into (2)
y = - 8(- 2) = 16
solution is (- 2, 16 )
