How do you graph ##x-y=7## by plotting points?

Convert the equation to . Determine two points. Plot the points and draw a straight line through the points.

Rearrange the equation to -intercept form, ##y=mx+b##, where ##m## is the slope and ##b## is the y-intercept.

##x-y=7##

Subtract ##x## from both sides.

##-y=-x+7##

Multiply both sides by ##-1##.

##y=x-7##

Since this is a linear equation, only two points are needed.
