(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the slope of the line that joins P (0,2) and Q (x, 2^x+1) for x ≠0. type the expression using x as a variable.

2. Relevant equations

Rise over Run?

3. The attempt at a solution

I have a picture of the graph but i don't really know what to do, Please help.

I graphed it at x= -3, -2 and -1 cause that was part 1

Okay so i just had a thought in my mind. So we can use limits to find the slope of the secant line, So would i use The limit of 2^x+1 as x approaches 0. But then the slope would be 1, And how would i write the expression in terms of x.

So for when x=-1 the rise/run is .5/1

x=-2 rise over run is .75/2

and when x=-3 rise over run is .875/3

but now how would i do the expression part?
