The y intercept is when x=0
x is the depdendent numer
when x=0 (or when no change has occured), the y intercept is te starting value
example
a car is at the 1 mile mark
if it goes 10 miles per hour, what mark will it be at in 10 minutes
distance=10x+1
1 is starting point, when x=0, or when the car hasn't traveld at all
yint is the initial value of the function
1800 - 1350= 450 3 months after the purchase he payed $450
450/3= $150 per month
1350 - 1050= 300 5 months AFTER THE PURCHASE he payed $300
300/2= $150 per month
^after 2 more months he payed $300^
$150 per months
Equation: (initial amount) - (150)M
M= amount of months after purchase
B = 1800 - 150M
