I solved the inequality and now I have to graph and shade it in.


Y<-5x-6
0<-5x-6

I used the test point 0,0 and substituted in y but how do I know if it's true or false?

  • Algebra -

    go to wolframalpha.com and type in

    plot y < -5x-6

    the equation y = -5x-6 is a line

    you want the whole area where y is less than that: below the line.

    If you subbed in (0,0) you get 0 < -6 which is false. (You have to sub in both x and y, not just y!)

    I don't get how you would know which way to shade the inequality when it's true or false. For example the inequality 2x+3y> 12 When I solve it it's y>-2/3x+4 But when I graph the line how would I know which side to shade?
