$y = \frac{4 x}{5} + 2$ $y=(4x)/5+2$

Explanation:

Lines are written in the form $y = m x + b$ $y=mx+b$ , where $x$ $x$ and $y$ $y$ are points on the line, $m$ $m$ is the slope, and $b$ $b$ is the $y$ $y$ -intercept. Since we're finding a general equation of the line, we don't have to touch $x$ $x$ and $y$ $y$ (which are general points).

We are told that the slope, $m$ $m$ , is $\frac{4}{5}$ $4/5$ and the $y$ $y$ -intercept, $b$ $b$ , is $2$ $2$ . Since lines are expressed as $y = m x + b$ $y=mx+b$ , we just make substitutions to get $y = \frac{4 x}{5} + 2$ $y=(4x)/5+2$ .
