For each one . . .
=> solve the equation for 'y'. That means massage it around until it's in the form of *** y*** = (thing1) x + (thing2).
=> When you do that, then 'thing1' is the slope of the line on the graph, and 'thing2' is the number where the line crosses the y-axis.
=> When you have those two numbers, drawing the line on the graph is a piece-o-cake.
you have to change all the equations to y=... to be able to graph them.
To solve an equation for 'y', rearrange it into the form y = ( t hin g 1 ) x + ( t hin g 2 ) to identify the slope and y-intercept. Isolate 'y' by moving other terms to the other side of the equation and then divide to solve. This will help you graph the equation accurately by using the slope and y-intercept.
