Question

what is the slope of this line?
0
$x=2$
$y=2$
undefined

Explanation:

Step1: Recall slope formula

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

Step2: Pick two points on red line

Choose $(0, 2)$ and $(2, 2)$

Step3: Calculate $\Delta y$ and $\Delta x$

$\Delta y = 2 - 2 = 0$, $\Delta x = 2 - 0 = 2$

Step4: Compute slope

$m = \frac{0}{2} = 0$

Answer:
