SO lets look at y > 2x - 4
00:03
Agile Mind Pg 167 #1

This time we need to exclude the y=2x-4, however, we need the line in order to know where to shade... so instead of a solid line we're going to use a dotted line
00:19
y=2x-4
00:41
y>2x-4
00:54
(0,0)
01:03
0>2(0)-4
01:08
0>-4
01:10
True
01:15
(5,1)
01:17
1>2(5)-4
01:22
1>10-4
01:25
1>6
01:28
False
01:32
This means that where the green dot is shows where all of the solutions to the inequality lie. just like with number lines when we colored the side of the dot that had the solutions, with lines, we have to color the whole side of the graph that has solutions, so lets color it in
