Anderson is a plumber and is paid a fixed amount just to make a house visit. The remainder of his fee, y, is determined by the number of hours that he works, x, as shown below.

Plumber Charges
A graph with hours worked on the x-axis and total paid on the y-axis. A line goes through points (0, 50), (10, 150), and (20, 250).

Which equation represents the graph?
y = 10x – 50
y = 10x + 50
y = 50x – 10
y = 50x + 10

y=10x+50

Explanation:

The line starts at point (0,50) which is the y intercept (how much he gets paid to visit house).The line crosses points (10,150) and (20,250) and the slope of these points are 100/10 which when simplified equals 10x which is how much money he gets paid by the hour(x=hours) so y=10x plus the y intercept y=10x+50

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
