# How do you graph f(x)=6x-4?

Jan 12, 2017

Plot the points $\left(0.7 , 0\right)$ and $\left(0 , - 4\right)$

Join them with a straight line.. You get the graph.

#### Explanation:

Let -

$y = 6 x + 4$

Find two points - x- intercept and y-intercept

x- intercept

At $y = 0$

$6 x - 4 = 0$
$6 x = 4$
$x = \frac{4}{6} = 2.3 = 0.7$

$\left(0.7 , 0\right)$

y-intercept

At $x = 0$

$y = 6 \left(0\right) - 4$
$y = - 4$

$\left(0 , - 4\right)$

Plot the points $\left(0.7 , 0\right)$ and $\left(0 , - 4\right)$

Join them with a straight line.. You get the graph.
