Find the equation of the line passing through (-2,8) and (5,-3)

y = -2/3x + 5

this is the slope intercept. -2/3 is the slope and 5 is where it intercepts the y axis.

hope this helps

We know:
397 total
53 fewer student tickets than adult tickets

Variables: A for adult tickets, S for student tickets

Known Equations:
a + s = 397
a = s + 53

Solving:
2s + 53 = 397 so 2s = 344 so s = 172

s + a = 397
172 + (172 + 53) = 397 so 172 + 225 = 397

Adult tickets sold: 225
Student tickets sold: 172
