Little Benny Franklin has $1.25 all in pennies in a jar. He decides to save 21 pennies every week and add them to the jar. In one year he will have $12.17 in the jar. Which numbers represent the slope and y-intercept?

Aslope = 1.25; y-int. = 21
Bslope = 21; y-int. = 1.25
Cslope = .21; y-int. = 1.25
Dslope = 12.17; y-int. = 1.25

The answer is b because the slope is the amount you add each time so you add 21 pennies each time, then the y intercept  is the initial amount which is 1.25

slope = .21; y-int. = 1.25 12.17 = .21x + 1.25

Where x = 52 weeks. Since the total and the original amount are in dollars, the 21 pennies per week should be written as .21.  So, the correct choice is C
