How to find the slope of a graph

There are 2 different ways, depending on the amount of data given;

1st way: When only the line on the graph is given (Without any coordinate points given) then the slope could be found out with the formula of Rise/Run, or Change in y / Change in x

2nd way: When a line and 2 coordinate points are given, the the formula that would be used is: , where X₁ and Y₁ are the coordinate points of the 1st given point, and X₂ and Y₂ are the coordinate points of the 2nd given point.

Hope this helps!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )
