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

Explanation:

consider y=mx+b
Given the points and the slope value (m), the remaining variable is b.

To find b plug in the point and m values:

$4 = \frac{2}{5} (- 1) + b$ $4= 2/5 (-1) +b$
$4 = - \frac{2}{5} + b$ $4= -2/5 + b$
$\frac{22}{5}$ $22/5$ OR $4 \frac{2}{5} = b$ $4 2/5 =b$
thus,
$y = \frac{2}{5} x + \frac{22}{5}$ $y=2/5x + 22/5$
