#### Answer

a.) 2
b.) 8
c.) -4
d.) y=2x+8

#### Work Step by Step

a.)
Two points that the line clearly goes through are (-4,0) and (6,20).
m=$\frac{y_2-y_1}{x_2-x_1}$
m=$\frac{20-0}{6-(-4)}$
m=$\frac{20}{10}$
m=2
b.) The line crosses the vertical axis (y-axis) when y=8.
c.) The line crosses the horizontal axis (x-axis) when x=-4
d.)
y-y$_1$=m(x-x$_1$)
y-0=2(x-(-4))
y=2(x+4)
y=2x+8
