Lilit [14]

Answer:

The slope is 2

Step-by-step explanation:

Given

x   y

2    3

5    9

Required

Determine the slope

First, we have:

(x_1,y_1) = (2,3)

(x_2,y_2) = (5,9)

The slope is then calculated as:

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

This gives:

m = \frac{9-3}{5-2}

m = \frac{6}{3}

m =2

<em>Hence, the slope is 2.</em>
