How to graph and calculate the slope of a line generated from the given points array?

I am new to desmos. I want to graph and calculate a line from the following array quickly

C=[27.94,31.34,34.625]
P=[0,-1,-2]

In google sheet, I can do that with this function

=SLOPE(C,P)

Thank you.

It looks like you’re wanting a regression like this, where C is the dependent variable, and P the independent.

Hi, thank you for your response. I did not know about ~ syntax, wow.

However, why is the value I am getting from google sheets is different than that in desmos?

C=[27.94,31.34,34.625]
P=[0,-1,-2]

# google sheets
=SLOPE(C,P)
= -3.3425

# Desmos
C ~ mP
m=-20.118

Oops! I left out the intercept, b, so it sort of included (0,0) as a data point. Here’s the updated with the same result.
