Question

If (-3, y) lies on the graph of y = 3x, then y = a. 1/27 b. -1 c. -27

Answer 1

Answer:

The correct value of y = -9.

Step-by-step explanation:

We know that there is a graph which represents the line $y = 3x$ and we are given a point (-3, y).

If this point (-3, y) lies on the graph, then we are to find the value of y.

For that, we will substitute the given coordinate of x in the equation of the line to find y:

$y = 3x$

$y=3(-3)$

$y = -9$

Therefore, the correct value of y is -9.

Answer 2

Answer:

y = -9

(-3 , - 9)

Step-by-step explanation:

Given that the equation of graph

y = 3x

and the co-ordinates are ( -3 , y )

where x = -3

So, put the value of x in the equation of graph above

y = 3(-3)

y = -9

The above answer is not in the options maybe the option is missing or something in question is missing. Let me know if question is not right so i can solve the right one for you.
