what is the slope of this line? is the slope positive or negative? a) positive b) negative slope: $\frac{rise}{run}$
Answer
Explanation:
Step1: Identify two points
Let the points be $(1, 2)$ and $(2, 1)$.
Step2: Calculate rise and run
Rise = $y_2 - y_1=1 - 2=-1$, run = $x_2 - x_1=2 - 1 = 1$.
Step3: Calculate slope
Slope $m=\frac{\text{rise}}{\text{run}}=\frac{-1}{1}=-1$.
Step4: Determine sign of slope
Since the slope is - 1, it is negative.
Answer:
Slope: -1 Sign of slope: b) negative
