Write an equation of the line that passes through the points (1,4), (3,7)
This will be
(7-4)/(3-1)
=3/2
...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
OOPS... Thanks EP!
