Let's take two points so that we can get the equation of the line which goes through those points. P1 (-9, -2), P2 (3, -17):
So, y is the line which goes through the first and last points of the chart.
To proof that the rest of points go through the line as well, we will evalute each point
Since the evaluation of these points don't correspond to the values of the chart we can assure that the relationship is not linear
Answer:
One student costs $3.75
Step-by-step explanation:
Unit rate is how much it is for 1 item. In this case, we want to know the cost for 1 student.
