Use the equation for the slope:
The two points are equal to (x1, y1) and (x2, y2).
So choose one of your points to be (x1, y1). Let's choose (4, -2). That means x1 = 4 and y1 = -2.
The other point would then be (x2, y2). So x2 = 24 and y2 = -17.
Now put these values in to the equation:
The slope is -3/4.

Answer:
105.12 ft²
Step-by-step explanation:
Let's first find the area of the rectangle.
ft², so the rectangle has an area of 80ft².
To find the area of the semi-circle, we find the area of a whole circle and divide by two.
The formula to find the area of a circle is . The radius is 4, as the diameter is 8.
Add 80 and 25.12:
