Look at the picture question and answer in there

x-intercept is for y = 0

y-intercept is for x = 0

We have x - 3y = -9.

Put y = 0 to the equation:

x - 3(0) = -9

x - 0 = -9

x = -9

Put x = 0 to the equation:

9 - 3y = -9

-3y = -9       divide both sides by (-3)

y = 3

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
