In this equation what do the letters x and y represent
y=mx+b
my understanding is that m is the slope and b in the y intercept
You are correct that m is the slope and b is the y-intercept at x=0.
The x and y are coordinates of a point on a rectangular coordinate system.
So let's say m=2 and b=1
Then at x=1 y=mx+b=2*1+b=3
Then at x=0 y=2*0+1=1.
Using these two points you can plot a line as shown below and note the slope of 2 (one unit to the right means two units up) and y-intercept=b=1 at x=0 or at point (0,1):
I hope the above steps were helpful.
