(x + 4) (x + 2)
=x^2 +2x + 4x + 8
=x^2 + 6x + 8
the other factor is (x + 2)

Answer:
y = -7x
Step-by-step explanation:
The line goes through the origin, so the y-intercept is b=0.
The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...
m = rise/run = -7/1 = -7
Then the slope-intercept form equation is ...
y = mx + b
y = -7x
