A man and his three children spent $40 to attend a show. A second family of three children and their two parents spent $53 for the same show. The system of linear equations shown represents this situation, where x is the cost of an adult ticket and y is the cost of a child ticket.

x+3y=40

2x+3y=53

How much will a family pay for 2 adult tickets and 4 child tickets?

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
