Question

What is the slope between (2,1); (5,9)

Answer 1

`(8)/(3)`

Explanation:

(2, 1)

(5, 9)

Find the slope

____________

When finding slope, we always have to follow the formula :

`(y^2-y^1)/(x^2-x^1)`

The y in the fraction are the second number within the coordinate points, while the exponents are the second number from the second point and the first number from the first point. The same goes for x. Therefore substitute x and y with their corresponding values :

`(9-1)/(5-2)`

`(8)/(3)`

Answer 2

Explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
