When Keisha installed a fence along the 200-foot perimeter of her rectangular backyard, she left an opening for a gate. In the d
iagram below, she used x to represent the length, in feet, of the gate.
.
What is the value of x, if the equation 2(x + 60) + 2(30) = 200 represents the Perimeter for the fencing of the backyard?

The x-intercept of -2 gives us an idea that point (-2,0) if found along the line. The y-intercept of -1, tells us that point (0,-1), this also tells us that b = -1.
Now that we have two points, we can solve for slope m
Now that we have both m and b. Substitute these values to the slope intercept form
