The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y

-3x+8
Answer:
If you need the answer as f by simplifying both sides of the equation and then isolating the variable, the answer would be:

Or, if you need to evaluate the function itself, the answer would be:

I can not see the trapezoid
$52 because 4 times 12 equals 48 so 100 minus 48 equals 52
