Hi  
Write the equation for the following relation
x	y
1	0
2	4
3	8
4	12
Plotting Points: One can see it is a Line:
m ={{{(y[1] - y[2])/(x[1] - x[2] )}}}
P(4,12)
<u>P(3, 8)</u>  m = 4/1,  m = 4
y = mx = b
y = 4x + b   |Using P(2, 4)
4 = 8 + b
-4 = b
y = 4x - 4 is the Equation of the Line satisfying the points given
Wish You the Best in your Studies.
