The equations below represent the total amount charged, Y, by two different plumbers as a function of the number of hours worked, X.

Plumber A: y = 20x + 60
Plumber B: y = 40x

The graphs of these functions cross at the point (3, 120). What does the point (3, 120) signify?

A. The point (3, 120) is the slope of the system of equations.

B. The point (3, 120) is the Y intercept of the system of equations.

C. The point (3, 120) is the solution for the system of equations.

D. The point (3, 120) is when the plumbers worked 120 hours.

C) The solution for the system of equations

Step-by-step explanation:

Point (3, 120) is where both lines intercept!

Basically, (3, 120) is where both equations are equal to each other.

(120 = 20(3) + 60) = (120 = 40(3))

We can test it!

120 = 20(3) + 60

120 = 60 + 60

120 (Correct)

120 = 40(3)

120 = 120 (Correct)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
