Question 805769: Solve each system by graphing , if possible
{3x - y = -3
{2x + y = -7
Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! 3 x + -1 y = -3 .............1
2 x 1 y = -7 .............2
Find the x & y intercept points by plugging x=0,y=0 in both equations.
equation I
when x= 0 y= 3 ,( 0 , 3 )
when y = 0 x= -3 ,( -1 , 0 )
Equation 2
when x= 0 y= -7 ( 0 , -7 )
when y = 0 x= -3.5 ( 0 , -3.5 )
You will observe that the point of intersection is -2,-3
The solution of the system is ( -2,-3 )
