You can identify the slope and y-intersept. The slope is 50 and the y-intercept is (0, 1200). You could also do the x-intercept, which would be the number of months passed when he pays off the debt fully. The x intercept would be (24,0)
Domain is everything below 0. Range is all real numbers. It is a function as it passes the vertical line test.
Steps:
1. Substitute the y in y=4x + 4 and put
X-6=-4x+4
2. Add 4x to both sides
3. 5x-6=4
4. Add 6 to both sides
5. 5x=10
6. Divide by 5 on both sides
7. X=2
8. Now to find the y, you substitute 2 for x in the problem y=x-6
9. Y=2-6
10. Y=-4
11. Your answer is
(2, -4)
If you look carefully at the grid, you will see that each increment is by 1/8.
That means that for the x-coordinate of P, you can count from -4/8 to get -5/8.
For the y-coordinate, you can count up from 0 to get 3/8.
Then, the answer is (-5/8, 3/8), or the third answer.
