Answer:
y=-4x-8
Step-by-step explanation:
use points (0,-8) and (-2,0) and plug into slope formula.
slope formula=(y2-y1)/(x2-x1)
(0-(-8))/(-2-0)=-4
you get y=4x+b
use point (-2,0) to find b
you get y=-4x-8
We can easily silve it by splitting the middle term or by using the discriminate method *
<h3>* <u>splitting</u></h3>
x 2 +3x -70
x2 + 10x - 7x -70
x(x + 10) -7(x +10)
(x / 7) ( x + 10)
x = 7 or -10
