Hope it helped,
Happy homework/ study/ exam!
Look at the picture.
The point-slope form:

We have the points (-3, -3) and (2, 0). Substitute:

Answer:
point-slope form: 
slope-intercept form: 
standard form: 
A rational number because any number between two integers is a fraction.
John has 17000 - 2500 = 14500 left to pay after the down payment
