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

146

Explanation:

To find any y-coordinate of a line, plug in the x-coordinate 50 into the equation and simplify. The result will be y.

Plug in x = 50 into y = 3x - 4.

y = 3(50) - 4

y = 150 -4

y = 146

The y-coordinate is 146.
