Line Eqns:system%28y=2x%2B1%28EQN1%29%2Cx%2By=-2%28EQN2%29%29
Subs't. EQN 1 in EQN 2:
x%2Bhighlight%282x%2B1%29=-2
3x=-2-1=-3----->cross%283%29x%2Fcross%283%29=cross%28-3%291%2Fcross%283%29
highlight%28x=-1%29, subst. in EQN 1:
y=2%28-1%29%2B1=-2%2B1
highlight%28y=-1%29
As we see the graph:
-------->RED Line>>>>EQN1 ; GREEN Line>>>>EQN 2
