# How do you graph the line x+4y=12?

Aug 25, 2017

Find 2 coordinates then plot those points to graph the line.

#### Explanation:

This is a linear equation so only 2 points are required to plot your graph.

Step 1 - isolate $x$ or $y$ on the left side of the equation. In this case $x$ is easier.

$x$$=$12$-$4$y$

Step 2 - find 2 values of $y$ and calculate the values of $x$. The easiest would be the $x$-intersect ($y$$=$0) and $y$$=$1.

$x$$=$12$-$4(0) => coordinate is (12, 0)
$x$$=$12$-$4(1) => coordinate is (8, 1)

Step 3 - plot your graph with these two points and connect the points and extend your line ( these points are part of the solution but not the end-points).
