are you able to identify the slope and y intercept?

jim_thompson5910 · Answer

hint: y = mx+b

m = slope
b = y intercept

unofficialllyy · Answer

slope is 40 
y intercept is 450

jim_thompson5910 · Answer

yep, 

slope = 40 ----> account grows by $40 each  week
y intercept = 450 ---> starting amount is $450
