Question

Find the slope

(2,8) (2,5)

a
0

b
-3/4

c
Undefined

Answer 1

To find the slope of a line given two points, we use the formula:

\[
\text{slope} (m) = \frac{y_2 - y_1}{x_2 - x_1}
\]

In this case, the two points are \((2, 8)\) and \((2, 5)\).

Plugging in the values:
- \(x_1 = 2\), \(y_1 = 8\)
- \(x_2 = 2\), \(y_2 = 5\)

Now calculate the slope:

\[
m = \frac{5 - 8}{2 - 2} = \frac{-3}{0}
\]

Since division by zero is undefined, the slope is **undefined**.

Thus, the correct answer is:

**c. Undefined**
