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.
