Question 335431: solve each system by graphing check your answer
(y=1/2x+2
(y=-x-1

i have tried this problem and got a point in between -1,-2 and -1,-1 but i really doubt its right because the other 3 problems i tried like this i checked with calculator and were wrong please help me!

Find the intercepts for both lines.
y=%281%2F2%29x%2B2
x-intercept:
0=%281%2F2%29x%2B2
%281%2F2%29x=-2
x=-4
(-4,0)
.
.
y-intercept:
y=0%2B2=2
(0,2)
.
.
.
y=-x-1
x-intercept:
0=-x-1
x=-1
(-1,0)
.
.
y-intercept:
y=-0-1
y=-1
(0,-1)
.
.
.
Plot the intercepts, lines, and look for the intersection point.
