What is the y-coordinate for the point (4, y) that is located on the line represented by 3x + y = 4?

1 answer

To find the y-coordinate of the point (4, y) on the line represented by 3x + y = 4, we need to substitute x = 4 into the equation and solve for y.

3x + y = 4

Substitute x = 4:

3(4) + y = 4

12 + y = 4

Now, isolate y:

y = 4 - 12

y = -8

Therefore, the y-coordinate for the point (4, y) on the line represented by 3x + y = 4 is -8.
