Solve the system of equations by graphing.
5x-9y=63
5x=9y+63
-----------------------------
Put the equations in slope-intercept form:
y = (5/9)x - 7
y = (5/9)x - 7
------------------------
The two equations are the same so the graphs are the same.
Let x = 0, then y = -7 giving you point (0,-7)
Let x = 9, then y = -2 giving you point (9,-2)
----------------------------------------------------
Plot the two points and draw a line thru them.
-------------
Solution: All points of the form (x, (5/9)x-7) where x is a Real Number.

these 2 graphs are identical
divide by -9
both graphs use this slope-intercept line, first point: (0,-7) 2nd point:(9,-2)
draw line u will notice its identical.
