Answer:
y = 4x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (0, 3)
m = =
= 4
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = 4x + 3 ← equation of line

Answer:
A = 156 square feet
Step-by-step explanation:
To find how much plywood Jesse will need to cover all the surface simply means we are to find the surface area.
The surface area of the triangular prism is given by;
A = (2 * (Area of the base)) + (Perimeter of base x height)
Now, area of the base=bh/2
b = 3 ft
h = 4 ft
area of the base = 3*4/2 = 6 ft²
perimeter of the base = L + b + h = 4 + 3 + 5 = 12 ft
height of the prism;h = 12 ft
Thus;
surface area of the triangular prism;
A = (2 * 6) + (12*12)
A = 12 + 144
A = 156 ft²
