Best ResponseYou've already chosen the best response.0use 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

Best ResponseYou've already chosen the best response.0Ok 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

Best ResponseYou've already chosen the best response.0You 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?

Best ResponseYou've already chosen the best response.0The 12/5 is the point you start graphing your line at, then you use the slope to start the line from there.
