Question

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?

Answer 1

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!)
