A local movie theater found that if the price of admission was $18, the attendance was about 850 customers per week. When the price of admission was dropped to $17 attendance increased to about 2250 per week. Write a linear equation for the attendance in terms of the price.
***
let x=price
let y=attendance
You have two points, (18, 850) and (17, 2250) on the graph y=mx+b
slope=(2250-850)/(17-18)=1400/-1=-1400/1
y=mx+b
y=-1400x+b
solve for b
850=-1400*18+b
b=850+25200=26050
equation: y=-1400x+26050
