Question 1109058
What are all the equations of the lines that intersect the graph of 5x+Y=14 at (2,4). 
Explain why. 
-----
m = (4-y)/(2-x) = (y-4)/(x-2)
m*(x-2) = y-4
----------
Pick any value for m and it passes thru the point.
There are an infinite # of them.
---------
The equation shown is not relevant, it's one possible line.
