You can put this solution on YOUR website!
y = cost
x = # of tickts
...
(1, 19.5) and (4, 78)
slope is %2878-19.5%29%2F%284-1%29+=+58.5%2F3+=+highlight_green%2819.5%29
...
highlight%28y+=+19.5x%29 is the equation
CHECK: if x = 4, y is 78
compared to y=mx+b, the slope, m is 19.5 and y intercept, b, is 0.
