Question

What is the slope of the line passing through the following points: `(8,10), (1, 3)`?

Answer 1

The formula for slope is `m = (y_2 - y_1) / (x_2 - x_1)`

Explanation:

`m = (y_2 - y_1) / (x_2 - x_1)`

The points `(x_1, y_1)` and #(x_2, y_2) are interchangeable.

`m = (3 - 10) / (1 - 8)`

`m = -7/-7`

`m = 1`

The line's slope is of 1.

Practice exercises:

1. Find the slope separating the points (2, -5) and (-4, -7)

2 . The following graph is of a linear function. Find its slope.

graph{y = -2/3x - 1 [-10, 10, -5, 5]}

Good luck!
