The equation you provided is:

$4x - 5y - 20 = 0$

We can rearrange this equation to express $y$ in terms of $x$ (slope-intercept form):

Step 1: Move the constant term to the other side

$4x - 5y = 20$

Step 2: Isolate $y$

$-5y = -4x + 20$

Step 3: Divide by $-5$

$y = \frac{4}{5}x - 4$

This is the equation in slope-intercept form $y = mx + b$, where the slope $m = \frac{4}{5}$ and the y-intercept is $-4$.
