The line thru (-3,0) and (-6,5) has this slope:

          5-0            5
m = ----------- = ------- = - 5/3
         -6-(-3)       -3

The y-intercept of the desired line is simply (0,0), and so b = 0 and the equation of this line is

y = (-5/3)x

Seventy concert tickets were sold for $550. Each adult ticket cost $9 and each children's ticket cost $5. Find the number of adu
mestny [16]
Total tickets = 70
Total cost = $550

Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4

Assume all 70 are child's tickets
5 x 70 = 350

But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50
So there are 50 adult's tickets.

70 - 50 = 20
And there are 20 child's tickets.
