use a table of values and substitute them into the equation
try x = 0 x = 1 and x = 2..... you'll get a corresponding y value for each x.... plot the points and then draw a line through the points...
or find the x intercept by letting y = 0 and solving...y intercept let x = 0 and solve for y
yeah i still dont understand how to graph it that way...

Ok first you have to get the y alone so subtract the x.
-5y = -4x + 12
Y cannot be positive, so you must divide/multiply by -1.
5y = 4x - 12
Y must be alone, you need to get rid of the five, so divide everything by 5.
Y= 4/5x - 12/5
Your slope is rise 4 run 5, and you need to graph at the point -12/5 on the Y axis, so thats -2.4
thank you for explaining it :)
Meant Y must be positive, wups.
wait so what are the points? im confused now
You go down to -12/5, or -2.4 on the Y axis. Then you use your slope to continue the line, going up 4 then over 5 times, and repeating. Get it?
The -12/5 is the point you start graphing your line at, then you use the slope to start the line from there.
