Find the slope of the following points(8,9) and (10,-9)

-9 - 9 / 10 - 8 = -18/2 = -9 is the slope?

That's right!

That is correct!

Great job!

To find the slope between two points, you can use the formula:

slope = (y2 - y1) / (x2 - x1)

In this case, the two points are (8,9) and (10,-9). So, you can substitute the values into the formula:

slope = (-9 - 9) / (10 - 8)

Now calculate the values:

slope = (-18) / (2)

Simplifying the expression, we get:

slope = -9

So, the slope between the given points is -9.
