Hi,

Solve the system of linear equations by graphing:

I. finding two ordered pairs (x,y) for each 

4x-y=0  If x = 0 ⇒ y = 0, Pt(0,0)  and If x = 1 ⇒ y = 4, Pt(1,4) 

2x-y=-2  If x = 0 ⇒ y = 2, Pt(0,2)  and If y = 0 ⇒ x = -1, Pt(-1,0) 

II.  Plotting the points and connecting with a line for each case.

III. Intersect at (1,4) which is the ordered pair that is the solution for this System
