# How do you graph 2x+4y=12 using the slope and y intercept?

Nov 20, 2016

plot $\text{ " (0, 6)," } \left(12 , 0\right)$

and draw a straight line through them

#### Explanation:

rearrange to the gradient -intercept form of the straight line

$y = m x + c$

$2 x + 4 y = 12$

$4 y = - 2 x + 12$

$y = - \frac{1}{2} x + 6$

to graph :

$y$- intercept is the $c$ value $c = 6$

to find second put put $y = 0$

$0 = - \frac{1}{2} x + 6$

$x = 12$

plot $\text{ " (0, 6)," } \left(12 , 0\right)$

and draw a straight line through them
