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

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)
