-- The original price was $82.
-- The dealer knocked ($82 - $65.60) = $16.40 off of the price because
he loves his customers so much and he wanted to make their lives easier.
-- The amount he knocked off is ( 16.40 / 82 ) = 0.2 = <em>20%</em> of the original price.
==========================================
Check:
If he reduced the original price 20%, then 80% of it must have been left.
80% of the original price = 0.8 x $82 = $65.60 It checks. <em>yay!
</em>

Answer:
y=3x+4
Step-by-step explanation:
first you find the slope by doing change in y over change in x. The change in y is 9 because 7-(-2)=9. The change in x is 3 because 1-(-2)=3. Then you do 9/3 which is 3, which is your slope, or m.
So now you know y=3x+b, then you substitute one of the points in for x and y, and you get 7=3(1)+b, where b is your y-intercept. then you solve, and find that b=4.
Now you put it into slope intercept form, which is y=mx+b, where m=3 and b=4, so you are left with y=3x+4.
