C. Above the dashed line.
It becomes:
y > 1/2x +3/2
(Dashed, shaded above)
5^2 + 3^2 (equals to 34) ; That's the wrong expression
It should look like this : (5+3)^2 (which equals to 64)
Slope intercept form is y = ax + b, where a is equal to the slope value, and b is equal to the y-intercept.
You have both the slope and y-intercept, which means that all you need to do is plug in the numbers to the equation in order to get your answer!
Let's plug in -7 for a, which gives you y = -7x + b.
Next, we'll plug in the y-intercept, which gives you y = -7x + 9.
Hope this helps!! :)
It would be 480, because I did it in Desmos
The answer to the question is 48cm^2
