Given pair of systems :
2x +y=8
and
y=2
To find the solution through graphing method
we plots the equation on the graph and the points at which the lines are intersect each other are called the solution of the system
Since the coordinates for 2x+y=8
at x =1,
2(1)+y=8
y=6
at x=2
2(2)+y=8
4+y=8
y=4
Thus the coordinates of 2x+y=8 is (1,6) & (2,4)
Plot them in th geraph for 2x+y=8
now for y=2
is the line parralle to x axis
So, the graph will be :
Since from the graph the line is cut at x=3 and y = 2
Answer : (3, 2)
