How to easily and accurately find intersection points on graphs

[JDW]

My daughter was working on her high school math homework this evening using her Prime. She typed in the following set of 4 inequalities:



When she pushes the Plot button, it draws the graph and she needs to find the 3 intersection points. I just told her to use the crosshair and circular movement button to jump to the points, but she complains that (a) moving the cursor around takes too long (it does), and (b) even when you move the crosshair over the intersection point the x & y data is not perfectly what it should be (it isn't). For example, if you look at the crosshair in the graph below, it should be x=0 & y=1.2 on that intersection point, but when using the Prime's crosshair manually I can only manage x=0.0035 & Y=1.19925. Sure, she could mentally just round off, but sometimes you want a precise number in cases where the intersection point is not so easy to determine by rounding.



Here's the second intersection point:



And here's the 3rd intersection point, which is supposed to be x=0 & y=0:



So what's the easy and fast way to jump to the exact intersection points on the graph using the Prime?

Thanks.
