Question 125339
Find an equation of the line containing the given pair of points.  Express your answer in the form x=a, y=b, or y=mx+ b

(-5, -5) and (5,5)

What is an equation of the line?
--------------------
slope = (5--5)/(5--5) = 1
Form is y = mx + b ; you know x,y and m; solve for b:
5 = 1*5 +b
b = 0
----------
EQUATION:
y = x
