How do you solve this? 18 " n=21

dalvyx [7]

$18 ^{n} =21$

$log(18) ^{n}=log(21)$

$n*log(18)=log(21)$

$n= \frac{log(21)}{log(18)}$

$n=1.053$

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from graph.</em>

Point (2, -1)

Point (-4, -3)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Substitute [SF]: $m=\frac{-3+1}{-4-2}$
Add/Subtract: $m=\frac{-2}{-6}$
Simplify: $m=\frac{1}{3}$
