What is the equation of the line that passes through (4, 3) and (2, 2) ? y= 1 2 x+2 y= 1 2 x+2 1 2 y= 1 2 x+1 y=2x−2

First find the slope by finding the change in y/change in x.
(2-3)/(2-4)
-1/-2
1/2

Now plug in one set of x and y values with the known slope to find the y intercept.
3= (1/2)(4)+b
3= 2+b
b=1

Final y= 1/2x+1
