Question

If (-3, y) lies on the graph of y = 3x, then y =

Answer 1

The value of y=-9

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

Answer 2

y = 3 x
(-3, y ) , x = -3
y = 3 · ( -3 )
y = - 9
