Question

What is the slope of the line that passes through the points left bracket, (9,1) and (10,−1)

Answer 1

Answer: m= -2

Explanation:

To find the slope of a line passing through two points, we can use the formula: slope = (change in y)/(change in x).

Using the points (9,1) and (10,-1), the change in y is -1 - 1 = -2, and the change in x is 10 - 9 = 1.

So, the slope of the line is -2/1 = -2.
