Question 672704: i need help with this question
3x-y=8
6x-2y=8
I have to solve the systems of equations by graphing
Answer by mananth(16946)   (Show Source):
You can put this solution on YOUR website! y= 3x -8
Assume values of x and plug in the equation to get values of y.
Plot the points
x 0 5 2
y= -8 7 -2
(x,y)(0,-8),(5, 7),(2-2)
6 x + -2 y = 8
y= 3 x -4
Assume values of x and plug in the equation to get values of y.
Plot the points
x 0 5 2
y= -4 11 2
(x,y) (0,-4),(5,11),( 2,2)
The slopes are same. The lines are parallel. Hence no solution to the system of equations
