Algebra-1

To determine which pair of points would yield a line with a negative slope, we use the formula for calculating the slope between two points and , which is .

Let's calculate the slope for each pair of points:

A. For the points and

Here , , , and .

The denominator is , so the slope is undefined. This represents a vertical line, not a line with a negative slope.

B.For the points and

Here , , , and .
