Question

Guys I wouldn't be asking if I had absolutely no clue on how to solve this but I am so please please help me!!!!

Answer 1

Its simple, so these are two "y=mx+b" form lines that are limited by the signs on the right. Your first line f(x)=-x-4 has to be between -3 and 1 on the x-axis.

You would plot a point at (0,-4) like normal, then go down one, right one as the slope is -1. you would make the dot at 1 though unfilled as x does not equal to 1. It is less than 1.  º Should look like the dot I just inserted.

The second line would be plotted, at (0,-6). You would then make a horizontal line between 1 and 5. º-------• (Should look like this)

       

IMPORTANT:

FILLED DOT - EQUAL TO

UNFILLED DOT - Not equal to
