To donate:

We will learn the steps to solve a multiple linear inequality problem:
1) put into y-slope intercept form (BOTH INEQUALITIES)
2) find the boundary line and graph (BOTH INEQUALITIES)
3) determine if it is a solid or dash line (LABLE BOTH INEQUALITIES)
4) determine which region satisfy the inequality (FOR BOTH INEQUALITIES)
5) note: it is easier to shade the regions that don't satisfy the inequality (especially BOTH INEQUALITIES)

Doc B, Why isn't line for 1 not broken as was line 2? I agree with your thoughts on math books. They cannot agree on the definition on a equal lateral triangle and an isosceles triangle. Thanks for your fine videos. I answered my question. Because of the equal sign and listened to the video. Thanks Doc.
