find the equation of the line   

1.  the gradient   m = rise/run            (4 -(-2))/(2-(-2))
                             = = 6/4 or 3/2

using the point slope formula with the point (2, 4)


y- 4 = 3/2(x - 2)

y = 3/2x + 3       line is in the form y = mx + b     b is the y-intercept

the y intercept is 3
