Line g passes through points (1, 1) and (10, 9). Line h is perpendicular to g. What is the slope of line h?

Step-by-step explanation:

Hi there!

First, let's calculate the slope of line g.

So, the slope of line g is

Now let's identify the slope of line h.

We are given that line h is perpendicular to line g.

Now, perpendicular lines have slopes that are opposite reciprocals.

This means we take a number, flop it over, and change its sign.

The slope of line g is

Now, we flop it over:

Then, we change its sign:

Thus, is our final answer.

Hope it helps! Enjoy your day! (:
