The slope of the "secant line" between the points (2, 5) and (x, x 2 + 1) in simplified form is, what?

2 answers

In "x 2 + 1", what is the operation symbol between x and 2?
change in y divided by the change in x.

the change in y is x^2+1-2
the change in x is x-2
I suspect that can be simpilified.
