Question

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

Answer 1

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.

Explanation:

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)) :}#
