Question 1204992: The director of a baseball camp estimates that 100 students will enroll if the tuition is $250. For each $20 increase in tuition, eight fewer students will enroll. Determine a linear function that will predict the number of students (y) who will enroll at a given tuition (x).

Question asks for a linear function. Description describes one point and a slope. Those go this way. A point (x,y) is (250, 100), and slope is -8%2F20=-4%2F10=-2%2F5.

Now, you know what to do with this, if you may start with the point-slope form.

y-100=-%282%2F5%29%28x-250%29.
Solve and simplify this for y, in the form of y=mx+b.
