Well, Here is how you do it!
Find the slope:
[tex] \frac{3-2}{3-2} = \frac{1}{1} = 1[/tex]
So the equation would look like this so far:
y = x + b
Now find the y-Intercept using a little common sense :)
(if x = 2 and y = 2, if x = 0 then y = 0)
b = 0
And the Equation looks like this:
y = x
Hope this helps!
