Answer:
<em>20 sq yd</em>
Step-by-step explanation:
To find the total amount of sq yd's of paint needed, you have to find the area.
The area of a triangle is: A = 1/2 bh
We know:
b = base = 8
h = height = 5
Plug in and solve:
A = 1/2 (8) (5)
A = 1/2 (40)
A = 20
Hi there!
Y-intercept:
Set the x value to 0:
y = 3(0) + 9
y = 9 --> (0, 9)
X-intercept:
Set the y value to 0:
0 = 3x + 9
Solve for x:
-9 = 3x
x = -3 --> (-3, 0)
