Question 532907
FALSE. Given a point (m,n), where m and n are not equal, and a slope 1, we can come up with an equation using the point-slope form. 

Let's choose the point (1,2).

Then   y-y1 = m(x-x1)

y-2 = 1(x-1)

y -2 = x-1

y = x + 1  <--- COUNTEREXAMPLE

That is an equation of a line with slope 1 and does not pass through the origin.
