Let
L=number of lower tickets sold
U=number of upper tickets sold
then
U=718-L...........(1)
and
9.50L + 8U=6249.50 ..........(2)
Substitute (1) in (2)
9.50L+8(718-L)=6249.50
isolate L and solve
1.5L=6249.50-8*718=505.5
L=505.5/1.5=337
U=718-L=381

Answer:
y = -1/17x - 17
Step-by-step explanation:
(9, -10) and (-8,-9)
= -1/17 use slope formula to find the slope
y + 9 = -1/17 (x + 8) plug numbers into point-slope formula
y + 9 = -1/17x - 136/17 use the distributive property to simplify
y= -1/17x - 17 solve and simplify
