Question

Solve the system by graphing:
2x-y=4
4x+y=2

Answer 1

draw the lines and find the point of intersection.
the best way to draw a line is e.g. to draw line 2x-y =4
1> first take x = 0 then y= -4 mark the point on the coordinate axis y at y= -4
2> 2nd take y=0 then x =2 mark the point on coordinate axis x at x =2

Answer 2

then finally join these points to get the line 2x - y =4
