X² + 10x + 25 = 16
x² + 10x + 25 - 16 = 0
x² + 10x + 9 = 0
(x + 1)(x + 9) = 0
x(x+9) + 1(x+9) = 0
x² + 9x + x + 9 = 0
x² + 10x + 9 = 0
(x + 1) = 0
x = -1
(x + 9) = 0
x = -9

Answer:
Step-by-step explanation:
I think in this question we have to find slope, if so, its y = 10x.
to find the slope just pick two numbers, i chose (2,20) and (7,70) and then put them in the slope formula y2-y1/x2-x1. That gave me 10. I hope its correct. :)
