One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.

Steven earns extra money babysitting. He charges $37.50 for 6 hours and $50.00 for 8 hours.

PilotLPTM [1.2K]

We have that
x------------------> represent the number of hours Steven babysits
y----------------- > represent the amount he charges

for x=6 hours
y=$37.50 ----------------> y/x=37.5/6=6.25
for x=8 hours
y=$50---------------------> y/x=50/8=6.25

therefore
y=6.25x

the answer is
y=6.25x
