First, you need to find out the are of the whole rectangle, which as you probably know, you just need to multiply base by height.
Then, you need to substract the are of the two little squares, which luckily are both the same size. To find out the are of a square you multiply a side twice.
Therefore,
Whole rectangle area:
(32+8) * (8+8) = 40 * 16 = 640 sq. ft.
Two small squares:
2 * (8 * 8) = 2 * 64 = 128 sq. ft.
We substract:
640 - 128 = 512 sq. ft.
First we need to find the slope of the line.
slope = y1-y2/x1-x2 = 4-1/3-(-3) = 3/6 = 1/2
So, the slope is 1/2
Now, we need to find the y-intercept by using the equation y=mx+b
y=mx+b
4=1/2(3)+b
4=3/2+b
-3/2 -3/2
5/2=b
So, the equation is y=1x/2+5/2 which is also C. y-3=1/2(x+1)

True
Step-by-step explanation:
Best to use a graphing calculator or graph it onto paper, after you change Point A after it reflected over the x - axis. The rule for reflection over the x-axis is (x, y) ---> (x, -y), so all you would need to do is change the positive 3 (the y value of A) into -3. So A' = (1, -3)
