We can tell that the $y$-intercept is $4.$ Now to find the slope, let's identify one more point on the line and use the slope formula.

As we can see the line passes through the points $(0,4)$ and $(4,2).$ Let's substitute them in the slope formula and simplify!$m=x_{2}−x_{1}y_{2}−y_{1} $

$m=4−02−4 $
