The area of the triangle is 31.5 ft^2

Step-by-step explanation:

Mathematically, the area of the triangle is the product of the base and the height divided by 2

From the given diagram, the base is of the measure 4 ft + 5 ft = 9 ft

The measure of the height is 7 ft

Thus, we have the area of the triangle as;

1/2 * 7 * 9 = 31.5 ft^2

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
