Answer:
C. Slope= -1/2, y-intercept= 2
Step-by-step explanation:
The y intercept is where it crosses the y axis
It crosses at y=2
We need two points to find the slope
(0,2) and (4,0)
We can use the formula
m = (y2-y1)/(x2-x2)
= (0-2)/(4-0)
=-2/4
=-1/2
It’s C because the y-intercept is where the point intersects on the y-axis and the slope goes up one and over 2 to the left making it negative

The area of a circle is area = pi x r^2
The full area = 3.14 x 20^2 = 1256 square feet.
The corner forms a 90 degree angle so the dirt area is 3/4 of a full circle.
Answer = 1256 x 3/4 = 942 square feet
Angle 3 is 78 degrees. same as angle 5.
3.5h+10=5.25h-11
21=1.75h
12=h
3.5(12)+10=5.25(12)-11
52=52
The answer is -9x + 6 2/3.
