Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
I used mathway to answer this and it said it was -6y(to the second power)+8y
Answer:
the point on the plane (-15, 5)
Step-by-step explanation:
These lines are:
1) a vertical line (x=-15) which implies that all x values of the points that it contains have coordinate x= -15
2) a horizontal line (y=5) which implies that all y values of the points that it contains have coordinate y = 5
Then the intersection must occur at x = -15 and y = 5, that is at the point (-15, 5)
