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=20x
y equals 20 x
y=100x
y equals 100 x
y=100+20x
y equals 100 plus 20 x
y=100x+20x
y equals 100 x plus 20 x

The mathematical equation that explains the function for Victoria's pay per week is:
\[ y = 100 + 20x \]
This equation reflects that she earns a flat rate of $100 plus an additional $20 for each hour she works (where \( x \) represents the number of hours worked).
