Question

can someone explain when i am trying to graph the system of linear inequalities of two variables..how would i work 4x-5ygreater or equal to 30?..

Answer 1

Rewrite 4x - 5y >= 30 as an equation of a line in slope intercept form so you can graph it. The line divides the x-y grid into two regions. Take any point (x,y), and plug that into the inequality, and evaluate to see if it is true. If true, then the entire region where the point is from satisfy the inequality, if false, the answer is the other region.
