3. (-4-3n)(-8) ≠ 32-24n, didn’t change the - to + when multiplying -3n by -8. answer is 32+24n

4. -1/4(x-8) = -1/4x+2 (no error)

5. 1/8(8x+16) ≠ x+8, divided by 1/2 instead of 1/8. answer is x+2

Line g passes through points (1, 1) and (10, 9). Line h is perpendicular to g. What is the
Sauron [17]

Answer:

\bold{The~slope~of~line~h~is~-\frac{9}{8}. }

Step-by-step explanation:

Hi there!

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

\displaystyle\frac{y2-y1}{x2-x1}

\displaystyle\frac{9-1}{10-1} \\
\displaystyle\frac{8}{9}

So, the slope of line g is \displaystyle\frac{8}{9}

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

\displaystyle\frac{8}{9}

Now, we flop it over:

\displaystyle\frac{9}{8}

Then, we change its sign:

\displaystyle-\frac{9}{8}

Thus, \displaystyle-\frac{9}{8} is our final answer.

Hope it helps! Enjoy your day! (:
