# Plotting Straight Line Graphs using Intercept Method Math Review

math tutorials > plotting straight line graphs using intercept method tutorial

## To plot a straight line you need only 2 points

The **x-intercept** is
the point where the graph cuts the x-axis **(x,0)**. The **y-intercept** is
the point where the graph cuts the y-axis **(0,y)**.

- To calculate the y-intercept, put x = 0.
- To calculate the x-intercept, put y = 0.
- Plot the 2 intercepts and join them with a straight line.

## Example

## Graph intercept problems for you to try

1) x + y = 7

2) y = -x + 2

3) 2y + 3x = 6
