7. A hot air balloon can travel up to 85 mph. If the balloon travels continuously at this speed, y=85x gives the number
of miles y that the hot air balloon would travel in x hours.
Fill in the table using the data points from the graph.
Determine whether x and y have constant change between
consecutive terms and whether they are in a linear function.
X
y

Solve the given system of equations. 2y= -x+9 , 3x-6= -15
