<em>Vertex: </em><em />
<em>The vertex is the top point where it curves!</em>
<em>Which is located at: </em><em />
<em />
<em>Y-intercept: </em><em />
<em>The Y-intercept is when a point doesn't move or left or right and just goes up or down!</em>

to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:
you can use cross multiplication to solve for x:
so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
