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

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
