You should always use a reference point such as (0,0) to determine which side of the line to shade. For example we have the equation y>2x-1 we then use the point (0,0) by substituting the point in the equation.
y>2x-1 -----> 0>2*0-1
we then solve and make sure the point satisfies the inequality.
0>2*0-1 ------> 0-1=-1 ----> 0>-1
We see that the point does satisfy the equation so we shade whatever side of the line that includes the point (0,0)
Hope this helps!
B. Make sure your cell phone is charged. You do NOT need your cellphone to be outside at all. So having it charged to go out has no reason to. I hope this helped! :)
