7.5 x 103 is the scientific notation of 7500
Answer:
Since the truck adds 22,000 PER YEAR, this would be the number we multiply by the variable depending on how many years they are calculating for. So we have y = 22,000x
The truck already has 40,000 miles on it so it s STARTING at 40,000, this is our y-intercept, or b.
Now we have y = 22,000x + 40,000
It moves five squares to the left because it is -5 so it’s decreasing
x=0
y=-2
You'd put them in an ordered point, so (0,-2).
Y=55x+200, you multiply the number of weeks by the amount of money, and add 200 because they started with that.
