Substitute 2 values for $x$ $x$ and solve for $y$ $y$ in order to find two points on the line and plot them. Then draw a straight line through them.

$y = - \frac{2}{5} x + 2$ $y=-2/5x+2$

Find two points on the line.

Point A:

$x = 0$ $x=0$

$y = - \frac{2}{5} \cdot 0 + 2$ $y=-2/5*0+2$

$y = 0 + 2$ $y=0+2$

$y = 2$ $y=2$

Point A $=$ $=$ $(0, 2)$ $(0,2)$

Point B:

$x = 5$ $x=5$

$y = - \frac{2}{5} \cdot 5 + 2$ $y=-2/5*5+2$

$y = - \frac{10}{5} + 2$ $y=-10/5+2$

$y = - 2 + 2$ $y=-2+2$

$y = 0$ $y=0$

Point B $=$ $=$ $(5, 0)$ $(5,0)$

Plot point A and B, then draw a straight line through them.
