How do you graph y=3/2x-1

On the Y-axis you graph -1. From there you go up three and two to the right and keep following that pattern

So you need to pick apart the equation to discover the slope and the y intercept.
following the formula y=mx+b 3/2x would be the slope and -1 would be the y intercept.
you would graph the point (0,-1) for the y intercept then go up three units and right 2 units and graph the point  (2,2). then you go up 3 units and right 2 units and graph the point (4,5) and keep repeating the pattern. after you've plotted all the points, you connect them all with a line. hope this helps!

Then just do it (lol)
