Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions. 

Below is the solution:

y = 3x
y = 3*-2 = -6

f (-2, y) lies on the graph of y = 3x, then y = -6

Answer 2

Answer:  The required value of y is - 6.

Step-by-step explanation:  Given that (-2, y) lies on the graph of the following line :

$y=3x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the value of y.

Sine the point (-2, y) lies on line (i), so the equation (i) must be satisfied by the point (-2, y).

Substituting the point (-2, y) in equation (i), we get

$y=3x\\\\\Rightarrow y=3\times(-2)\\\\\Rightarrow y=-6.$

Thus, the required value of y is - 6.
