Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
I am trying to find the intersection of -0.171x-+43.43 and -0.146x+39.83. I entered them into my "y=" and clicked graph. I then plug in "2nd trace, and click on intersect" But i get a message saying "NO SIGN CHANGE" Whats going on here??
-0.171x+43.43 and -0.146x+39.83
i tried that and i got the same thing, but i noticed that if you change your window so it fits more of the graph on the right, were you can actually see the lines intersect, then you can get the intersection.
oh, and by the way, the intersection is (144, 18.806)
