I think first you need to get it to y equal first take away 4x form both sides then divide by -5 then what ever is beside the x is the x intercept I hope I helped
What Is The X-intercept, And Y-intercept Of 4x-5y=20?
4x - 5y = 20 (your equation)
4x/20 - 5y/20 = 1 (divide both sides by 20. This puts the equation in what I would call "intercept form".)
x/5 - y/4 = 1 (simplify)
x/5 + y/(-4) = 1 (go the last step)
"Intercept form" is this:
x/(x-intercept) + y/(y-intercept) = 1
We immediately recognize that
x-intercept = 5
y-interctpt = -4
4x/20 - 5y/20 = 1 (divide both sides by 20. This puts the equation in what I would call "intercept form".)
x/5 - y/4 = 1 (simplify)
x/5 + y/(-4) = 1 (go the last step)
"Intercept form" is this:
x/(x-intercept) + y/(y-intercept) = 1
We immediately recognize that
x-intercept = 5
y-interctpt = -4
