You can put this solution on YOUR website!
Graph: y%3C2x%2B1-> this is the graph of a line
just graph y=2x%2B1 and solution will be shaded area under this line
find two points that lie on this line and draw a line through
x-intercept and y-intercept are easiest to find
set y=0 and find x-intercept
0=2x%2B1=>2x=-1=>x=-1%2F2
set x=0 and find y-intercept
y=2%2A0%2B1=>y=1
points are:(-1%2F2,0) and (0,1)
plot them and draw a line through


2.
+y%3E-%281%2F4%29x%2B2
set y=0 and find x-intercept
+0=-%281%2F4%29x%2B2
+%281%2F4%29x=2
+x=2%2F%281%2F4%29
+x=8
set x=0 and find y-intercept
+y=-%281%2F4%290%2B2
+y=2

points are:(8,0) and (0,8)
plot them and draw a line through
