How do you graph the line 3x + 2y = 12?

Nov 6, 2016

The gradient is $- \frac{3}{2}$ and the y- intercept is 6

Explanation:

Rearrange the equation into the form y= mx + c
$3 x + 2 y = 12$
$2 y = - 3 x + 12$
$y = - \frac{3}{2} x + 6$

The graph has a gradient of $- \frac{3}{2}$ and crosses the y axis at 6

Or choose 2 points on the graph.
When x=0 , y = 6
When y=0, x= 4
Plot the points and you have your graph
