Hello.
We have a point that the line passes through and its slope.
Let's write the equation in Point-Slope Form:
y-y₁=m(x-x₁)
In this case,
y₁=2
m=
x₁=4
Plug in the values:
This is point-slope form. Now, what about Slope-Intercept?
First, we should distribute :
Add 2 to both sides:
Simplify:
I hope it helps.
Have a nice day.
Answer:
625 unit²
Step-by-step explanation:
Surface area of a rectangular pyramid :
Area of base * 4(area of triangular side)
Area of base = length * width
Area of base = 15 * 15 = 225
Height of triangular side = 15
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 *15 * 15 = 112.5 unit²
Surface area = 225 + 4(112.5)
Surface Area = 225 + 450
Surface Area = 625 unit²
