Question

graph the equation y =|a|x when -1 15 years ago

Answer 1

Well, you're told 'a' has to be between -1 and 0, NOT inclusive of these two values. You're also told that \[y=|a|x\]which means you're taking the magnitude of 'a' (i.e. the square root of the square (basically, here, the positive version of the number)). The graph is going to be a series of graphs (infinitely many) but you're not going to construct infinitely many graphs. All you need to do is plot the boundary graphs - i.e. when a=-1 and when a = 0, and you'd draw them with dashed lines since the equation can't actually take a=-1 and a=0 (if there were less than or equal signs, you would draw solid lines). So you should have something like the attached (to come):

Answer 2

The horizontal line is y=0 (since a=0) and the one above is y=x, since a=-1 and y=|-1|x=1x=x.
