Question 359457
Please help me graph the line -4x+5y=20.
------
If x = 0, y = 20/5 = 4, giving you point  (0,4)
---
If y = 0, x = 20/-4 = -5, giving you point (-5,0)
-------------------------
Plot the two points and draw a line thru them:
{{{graph(400,300,-10,10,-10,10,(4/5)x + 4)}}}
-------------
Cheers,
Stan H.
