A shoe store made a profit of $14,510 in 1988 and a profit of $21,260 in 1993. Write an equation that gives the profit, y, in tems of the year, x. Let x=0 correspond to 1980 and assume that the profit followed a linear pattern.

How would I do that. Dont just tell me the answer show me how. My math teacher is an idiot.

thats easy, just make a line graph, starting at 1980 and going until 2000.

label each individual year between 1980 and 2000 on the x axis.

y axis label money values, going up increments of $5,000, starting at 0 and ending at $25,000

mark down a dot at $14,510 on the 1988 date, and $21,260 on the 1993 date

Draw a line between the two, and that is the linear line he wants. keep that line going until you reach 1980. hatever level its at is how much they made in 1980

now find out how much more of a profit they make every year, and that is your x value.

so if you want to figure out how much they made in, say, 1989, you take 9 and multiply it by x, then add that number to what they made in 1985, and you have the answer

Equation is y=1350x+3710 if you still need it...at least that's what I got...and I'm pretty sure is right.
