Answer:
Before we graph we know that the slope, mx, could be read as
. To graph the the equation of the line, we begin at the point (0,0). From that point, because our rise is negative (-1), instead of moving upwards or vertically, we will move downards. Therefore, from point 0, we will vertically move downwards one time. Now, our point is on point -1 on the y-axis. Now, we have 2 as our run. From point -1, we move to the right two times. We land on point (2,-1). Because we need various points to graph this equation, we must continue on. In the end, the graph will look like the first graph given.
For the equation y = 2, the line will be plainly horizontal. Why? Because x has no value in the equation. The variable does not exist in this linear equation. Therefore, it will look like the second graph below. We graph this by plotting the point, (0,2), on the y-axis.

Given:
Area of rectangular pool = 640 square feet
The length is 12 feet shorter than the width.
To find:
The length and width of the pool.
Solution:
Let width of the pool = x feet
Then, Length of the pool = (x-12) feet
Area of a rectangle is
Area of pool is 640 square feet. So,
Splitting the middle term, we get
Using zero product property, we get
Dimensions cannot be negative. So, x=32.
Now,
Width of the pool = 32 feet
Length of the pool = 32-12 = 20 feet
Therefore, the length of the pool is 20 feet and width is 32 feet.
