...continuing on CTG work  above      

Cal has calculated the slope as 3/2 = m   in the equation of your line   y = mx+b

 

so now you have    y = 3/2 x + b      sub in either of the points to calculate 'b'

                               4 = 3/2(1) + b

                                                   b = 5/2           y = 3/2 x   + 5/2
