Y=Mx+b (m is slope, b is y-intercept)
Tickets to a band concert cost $10 each. The equation y = 10x represents total cost, y, of x tickets. Which graph shows ordered
pairs represented by this equation?

Answer:
the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.
Step-by-step explanation:
Given the function equation
- y = 10x
Given that the cost of each ticket is $10.
It means:
at x = 0, y = 10(0) = 0 ∵ cost of 0 ticket
at x = 1, y = 10(1) = 10 ∵ cost of 1 ticket
at x = 2, y = 10(2) = 20 ∵ cost of 2 tickets
at x = 3, y = 10(3) = 30 ∵ cost of 3 tickets
at x = 4, y = 10(4) = 40 ∵ cost of 4 tickets
at x = 5, y = 10(5) = 50 ∵ cost of 5 tickets
Now, observe the ordered pairs points on the right-hand graph of the first diagram.
This graph has the following ordered pairs:
- (0, 0) i.e. at x = 0, y = 10(0) = 0
- (1, 10) i.e. at x = 1, y = 10(1) = 10
- (2, 20) i.e. at x = 2, y = 10(2) = 20
- (3, 30) i.e. at x = 3, y = 10(3) = 30
- (4, 40) i.e. at x = 4, y = 10(4) = 40
- (5, 50) i.e. at x = 5, y = 10(5) = 50
Thus, the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.
