Question 318701: They are asking me to sketch the graph of each linear inequality one example is y>-2/5x +1 can you give me a way to solve this problem and the rest of them
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
sketch the graph of each linear inequality one example is
y>-2/5x +1
---------------
You have to graph the boundary of the inequality.
The boundary is y = (-2/5)x + 1
---
You need two points:
(0,1) and (5,-1)
Plot those and draw a dashed line thru them.
That is the boundary and it is not part of the solution set.
---------------
The solution is on one side or the other of the boundary.
---
Test (0,0) in the inequality.
You get 0 > (-2/5)*0 +1
0 > 1
---
That is false. That means the solutions are not on the
side of the boundary that contains (0,0).
It is on the other side.
