Please, can someone help?
Why I am having different results?
1) When using Home plot with (2X(Sqr) – 9X) the Slope result is -1
2) When using CAS with SLOPE(2X(Sqr) – 9X) the result is 0
3) When using Home with SLOPE(2X(Sqr) – 9X) the result is -1
Solved! Go to Solution.

Thanks for your explanation
it is still showing 0
I have another post as follows:
Please, how to know when I can or cannot use the CAS mode?
In other words, which functionally must use the CAS mode?
I have an HP Prime for two weeks, and I am still having a problem figuring out it.
This calculator can cause a misleading calculation, with my 50G I have no problem.
I will try one week more before returning it, please can someone help?

There is two use of slope in CAS, one is low case "slope" as below
And Upper case "SLOPE" as Below
When you use upper case SLOPE command with uppercase variable it too produce same answer, in CAS
Hope this helps
