Line eqn: x%2B2y=-1
Via Slope-Intercept Form: y=mx%2Bb, wheresystem%28m=xlope%2Cb=Yintercept%29
2y=-1-x---->cross%282%29y%2Fcross%282%29=%28-1-x%29%2F2
y=%28-1%2F2%29x-%281%2F2%29
f%28x%29=0
y=%28-1%2F2%29%280%29-%281%2F2%29=highlight%28-1%2F2=y%29
f%28y%29=0
0=%28-1%2F2%29x-%281%2F2%29
%281%2F2%29x=-1%2F2

highlight%28x=-1%29
see graph:
