9514 1404 393
Answer:
- slope: 2
- y-intercept: 4
Step-by-step explanation:
The y-intercept is where the line crosses the y-axis. This graph has a y-intercept of 4. The point coordinates there are (0, 4).
__
The slope is the ratio of rise to run. It is convenient to identify places where the graph crosses grid intersections. This graph has a rise of 2 units for a run of 1. So, the slope is 2/1 = 2.
The slope is 2; the y-intercept is 4.

Answer:
The area of the rectangular playroom is 260 feet² .
Step-by-step explanation:
Given:
The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.
Now, to find its area we need the length .
So, putting the formula of perimeter we get it's length:
Let the length be l .
Perimeter = 2( length + width)
subtracting both sides from 20:
Dividing both sides by 2:
Length is 26 feet.
And, to get the area we put the formula of finding the area:
Therefore, the area of the rectangular playroom is 260 feet² .
