Answer:
y = -3/4x -4
Step-by-step explanation:
y = -3/4x + b
-1 = -3/4(-4) + b
-1 = 12/4 + b
-1 = 3 + b
-4 = b
y = -3/4x -4
By the formula for the area of an equilateral triangle (s^2sqrt(3)/4), the area is sqrt(3)/4.

Answer:
50 in²
Step-by-step explanation:
→ Find the area of the square
5 × 5 = 25
→ Find the area of the triangle
( 0.5 × 5 × 5 ) = 12.5
→ Double the answer as there is 2 triangles
12.5 × 2 = 25
→ Add the areas together
25 + 25 = 50 in²
When using the formula that lets you solve for the area of a traingle, you use
area = 1/2 base + height
which led me to solve and get 32.13
