Do it like this:
Given 2 points example.
Find the equation of the line thru the points (2,1) and (3,5)
---------------------
This is a 2 step process. First find the slope of the line thru the points.
slope, m = diffy/diffx
m = (5-1)/(3-2)
m = 4
---------
Now use y = mx + b with either point to find b, the y-intercept.
y = mx + b
5 = 4*3 + b
b = -7
-------
y = mx + b
y = 4x - 7 is the answer.

Find an equation of the line containing the give pair of points
(-6,-6) and (7,7)
-----------------------
slope = (7--6)/(7--6) = 13/13 = 1
----
Form: y = mx + b
You have m = 1 and y = 7 when x = 7.
Substitute and solve for "b":
7 = 1*7 + b
b = 0
--------------
Equation:
y = x

step 1 - find the slop using
we get
simplified, we get
---
step 2 - find b
using y = mx + b, we get
so
b = 0
---
we get
y = 1x + 0
