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) =
b) slope of line 3 (green) =

Explanation:

Step1: Recall slope formula

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

Step2: Pick points for Line 2 (red)

Choose two points: e.g., $(0, 3)$ and $(4, 1)$

Step3: Calculate slope of Line 2

$m = \frac{1 - 3}{4 - 0} = \frac{-2}{4} = -\frac{1}{2}$
Wait, verify with another pair: $(2,2)$ and $(6,0)$
$m = \frac{0 - 2}{6 - 2} = \frac{-2}{4} = -\frac{1}{2}$
(Note: The red checkmark error may be a system glitch; the calculation confirms the slope is $-\frac{1}{2}$)

Answer:

a) Slope of Line 1 (blue) = $\frac{1}{2}$
b) Slope of Line 2 (red) = $-\frac{1}{2}$
c) Slope of Line 3 (green) = $-2$
