1. find slope x=tickets sold y=money made slope=(y2-y1)/(x2-x1) take any point (5,23.75) and (10,47.50) input (note, (x,y)) (47.50-23.75)/(10-5)=23.75/5=4.75 slope=4.75 y=mx+b m=slope b=yintercept y=4.75x+b input 47.5=4.75(10)+b 47.5=47.5+b b=0
equation is y=4.75x if ticket sold is 24 then x=24 y=4.75(24) y=114 answer is $114
2. points (0,56.00) and (3,45.5) slope=(y2-y1)/(x2-x1) slope=(45.5-56.00)/(3-0)=-3.5 y=-3.5x slope=-3.5 logic it yourself equation is y=-3.5x+0 y intercept is when x=0 so when the start of it was or when time=0 x intercept is when y=0 is when he has no money left
1.a. rate of change=4.75 b. $114
2. a.do this yourself, (desmos graphing calculator) b. slope=-3.5 (duh, means money goes down with time) c. equaiton is y=-3.5x+0, xint meanss when he has no money, y int means when time=0 or when it started
