I don’t really know it sry
(-7,-3) (-1,0) (9,5) and (13,7)
Ok so basically the number by the X is your slope (m) and the other number is your y-intercept (b) so for example the first question your slope (m) 2/3 and your y-intercept (b) -2
Part A:
Given that <span>a dinette table with a cash price of $200 is purchased at $8.50 down and $11.00 per month for 24 months
The total installment price is given by

Part B:
