The simplest way to do this is to use the formula where

\frac{y(2)-y(1)}{x(2)-x(1)} 

is equal to slope. 

(2--6)/(4--2)= 8/6. 

Hope this helps!

Answer:

Area = 16sq inches

Perimeter =  16 inches

Step-by-step explanation:

The shape of body is a square:

 Area = S²

 Perimeter = 4S

S is the side length

So;

      S  = 4inches

Therefore;

       Area = S²   = 4²   = 16sq inches

       Perimeter  = 4S  = 4(4)  = 16inches

Sam is paid $50 per room that he paint and he paint room in exactly two hours on sunday sam hopes to make at least $150 painting
Gnesinka [82]

Since Sam can paint 5 rooms in 10 hours, since:

\frac{10\text{hours}}{2\text{hours}}=5\text{ rooms}

then Sam would have to paint at least 3 rooms to make $150.

The range of hours would be from 6 to 10 hours, since 3 rooms takes 6 hours to paint.
