Question

A point on the line y=3x-4 has an x- coordinate of 50. what is the y-coordinate of this point

Answer 1

In order to calculate y-coordinate, just substitute the value of x-coordinate into the expression:
y = 3x - 4
y = 3(50) - 4
y = 150 - 4
y = 146

In short, Your Answer would be 146

Hope this helps!

Answer 2

The y-coordinate of the point is 146
