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

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

Let -

$y = 6 x + 4$ $y=6x+4$

Find two points - x- intercept and y-intercept

x- intercept

At $y = 0$ $y=0$

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

$(0.7, 0)$ $(0.7, 0)$

y-intercept

At $x = 0$ $x=0$

$y = 6 (0) - 4$ $y=6(0)-4$
$y = - 4$ $y=-4$

$(0, - 4)$ $(0, -4)$

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

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