# How do you graph the equation y=-5/4x-3?

Select a couple (arbitrary) values for $x$ and for each solve to get corresponding $y$ values; plot each set of coordinates; draw a line through those coordinates.
I used $x = 0$ and $x = 4$ as being fairly easy values to solve for $y$:
color(white)("XXX"){: (underline(x),color(white)("XX"),underline(y)), (color(red)0,,color(red)(-3)), (color(green)(4),,color(green)(-8)) :}
