Answer:
y=10x+50 is correct equation.
B is correct
Step-by-step explanation:
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,
We are given a graph to choose correct equation.
From graph we find two points on graph and then find the equation.
(0,50) and (20,250)
where, x represents number of hours worked.
y represents total earn by plumber.
Using two point formula to find equation of line.
[tex]y-50=\dfrac{250-50}{20-0}(x-0)[/tex]
[tex]y-50=10(x-0)[/tex]
[tex]y=10x+50[/tex]
Hence, y=10x+50 is correct equation.
