wouldnt it be 40? since its adding 5 more each weak by 8 weeks 8x5= 40
OpenStudy (isaiahjwolfe):
You take the information and put it into the average rate of change equation, y1 - y2/x1 - x2
OpenStudy (vickyisthesmartone123):
ok one of you is correcti dont know whois thoi need an answer deadly roses do you think he is correct or u?
OpenStudy (isaiahjwolfe):
So 25 - 20/1 - 0 = 5, that's the slope of the line.
OpenStudy (deadly_roses):

You can also tell because he increases the number of push-ups he does by 5 each week. So the slope will increase by 5.
OpenStudy (isaiahjwolfe):
