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 on
e year he will have $12.17 in the jar. Which numbers represent the slope and y-intercept? A) slope = 1.25; y-int. = 21
B) slope = 21; y-int. = 1.25
C) slope = .21; y-int. = 1.25
D) slope = 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
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
