This is an MCQ-based quiz for GRE on **How To Find The Equation Of A Line.**

The general equation of a straight line is **y = mx + c**, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

What line goes through the points (1, 3) and (3, 6)?

Which line passes through the points (0, 6) and (4, 0)?

What is the equation of the straight line passing through (–2, 5) with an x-intercept of 3?

Let y = 3x – 6. At what point does the line above intersect the following: 2x=2y/3+4

A line is defined by the following equation:
