4. Jada borrowed $1,000 for a new bike but had to pay back $1,000. How much interest does she have to pay? If her interest rate
is 5%, how long will it take her to pay off the loan and interest? How much would she save if she borrowed the $1,000 at 4% for the same amount of time?
6x + 4y = 8...subtract 6x from both sides 4y = -6x + 8....now divide both sides by 4 y = (-6/4)x + 8/4...reduce y = -3/2x + 2 <=== slope intercept form
