Answer:
y=[tex]\frac{1}{2}[/tex]x-8
Step-by-step explanation:
To solve this, you have to use the formula [tex]\frac{x_{2} -x_{1} }{y_{2} -y_{1}}[/tex] to find the slope.
[tex]\frac{0+4}{-8-0}[/tex] = 4/-8 = -1/2
so the slope is -1/2
Now, you plug your values into the formula y=mx+b
m = slope = 1/2
b = y-intercept = -8
so the final formula is y=[tex]\frac{1}{2}[/tex]x-8
