Answer:
The value of y=-9
Step-by-step explanation:
If (-3, y) lies on the graph of y = 3x
If any point satisfy the equation or graph. We get true for that point.
Now, we substitute the point into equation and left side is equivalent to right side.
Put x=-3 and to solve for y
y=3(-3)
y=-9
If x=-3 then y=-9
Hence, The value of y=-9
B. The cost for x children and y adults to go to the movies if the adult tickets are $11 and the child tickets are $6
