The amount needed to purchase materials needed to cover the area of the triangular flag is: $54.
<h3>What is the Area of a Triangle?</h3>
Area of a triangle = 1/2(bh)
Given the dimensions of the flag as the following:
base (b) = 18 in.
height (h) = √(41² - 9²) = 40 in.
Area of the flag = 1/2(18)(40) = 360 in.²
Cost of material needed = (360)(0.15) = $54

Answer:
y = 4x - 2
Step-by-step explanation:
slope = 4
y -6 = 4 ( x- 2 )
distribute the 4 to ( x - 2 )
y - 6 = 4x - 8
add 6 to both side
y = 4x - 2
