Question

use the graph, given above, to find the slope of each line.
a) slope of line 1 (blue) =

b) slope of line 2 (red) =

c) slope of line 3 (green) = -2

Explanation:

Step1: Recall slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$

Step2: Pick points on Line 2

Choose two clear points on the red Line 2: e.g., $(0, -1)$ and $(2, -2)$

Step3: Calculate slope values

Substitute into formula: $m = \frac{-2 - (-1)}{2 - 0} = \frac{-1}{2}$

Answer:

$\boldsymbol{-\frac{1}{2}}$
