Question

what is the slope of this line? is the slope positive or negative? a) positive b) negative slope: $\frac{rise}{run}$

Explanation:

Step1: Select two points on the line

Let's take the points (-2, 1) and (-1, -2).

Step2: Calculate the rise and run

Rise = change in y - values = -2 - 1=-3. Run = change in x - values=-1-( - 2)=1.

Step3: Calculate the slope

Slope $m=\frac{\text{rise}}{\text{run}}=\frac{-3}{1}=-3$. Since the slope is negative, for the second - part of the question, the slope is negative.

Answer:

Slope: -3
Is the slope positive or negative: b) negative
