Question

how would I graph -5x-4y > -20

Answer 1

Put in y = mx +b. Add the 5x to remove it from that side. You get -4y > -20 + 5x, now if we divide by -4 you get y < 5 -(5/4)x (Make sure to flip the inequality symbol as you just divided by a negative) To make this form more similar just rewrite it y < -(5/4)x + 5. As Y is less than this, graph it and shade below the line.
