Question

points (1,3) and (5,3) lie on line r. what is the slope of the line that is parallel to r?​

Answer 1

First we must find out the slope of the points

The equation for slope is

$\frac{y_{2} - y_{1}}{x_{2}-x_{1}}$

Let's plug in our points

$\frac{3 - 3 }{5 -1 }  = \frac{0}{4}$

Our slope is 0

When lines are parallel, that means we have they have the same slope

So a line that is parallel to r would have a slope of 0!
