=Example 2:Tell whether the orderd pair is a solution of the given system.=

(0,0); {y>-x-1 y<2x+4}

step 1: 0,0 is the x,y so subsitute both for x and y.

step 2: the problem now reads 0>0-1 0<2(0)+4 step 3:distribute 2(0) witch is 0, the problem now reads:0>0-1=-1 0<0+4=4 step 4: both of the inequalities are true so the ordered pairs work for the inequality.
