Question

A coordinate plane is shown the x-axis labeled from 0 to 40 in increments of 5 and the y-axis labeled from 0 to 900 in increments of 100. An upward slanting line is plotted. The line starts at left parenthesis 0 comma 100 right parenthesis and ends in an arrowhead point at left parenthesis 40 comma 900 right parenthesis.

Victoria gets paid $100 as a flat rate each week, as well as $20 per hour. Let y equal the amount Victoria gets paid per week and x equal the number of hours she works per week. Given that the graph shows the set of all solutions, what is the mathematical equation that explains the function?

y=100x+20x

y=100x

y=100+20x

y=20x

Answer 1

The correct equation that explains the function is y=100x+20x. This equation represents the flat rate of $100 per week plus an additional $20 per hour worked.
