Please explain steps to graphically solving the following set of equations:
2x + 4y = -7
5x - 7y = 25
--------------
To solve the set graphically, you have to graph both equations.
They're linear, so the graphs are straight lines. 2 points for each eqn are sufficient to fix a straight line.
Find 2 points.
draw a line thru the 2 points.
Do the same for the other eqn
Where they intersect is the solution
------------
you can go to www.padowan.dk.com/graph/ and DL (free) software that will make the graphs for you.
