Mr. smith junior wishes to buy a used car in a year's time when he turns 18, and he is willing to spend $5,000. he plans to work part-time and put all his monthly earnings into a bank account that will pay 0.5% interest per month. how much must he earn per month in order to be able to purchase the car in one year's time? the correct answer is $405.33 and not $430.33. how do we get to this?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

he earned 78.75 in interest.
