# How do you find the slope of (1,5), (-8,2)?

##### 2 Answers

Slope =

#### Explanation:

To find the slope for any 2 points

slope formula:

For our case, points are (1,5) and (-8,2)

slope

The gradient (slope) is

#### Explanation:

Like the gradient on a hill, the slope (gradient) is the amount of change in the up or down for the given amount of along as you read from left to right.

Let the gradient be

I have reversed the order of your points so that the

Let the first point be

Let the second point be

But

Note that 2 minuses is the same as a plus.

But

So the gradient (slope) is

This means that if you move to the right by 3 you have gone up 1

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Suppose the gradient had been

This would mean that you go to the right by 3 but you go down 1.

Negative gradient is a downward slope ( left to right)

Positive gradient is an upward slop (left to right)
