According to the graph what is the value of the constant in the equation below

The width is the x-value, meaning that the constant has to be divided by the x-value to get the y-value (height), so take (5,20) for example.

The equation would be 20=(x/5). Multiply both sides by 5 to get x by itself. This gives you that x=100. The constant is 100.

Therefore, the answer is C: 100.
