Answer: -5

Step-by-step explanation:

The formula for calculating the slope of a line is given as :

m=\frac{y_{2} }{x_{2}} - \frac{y_{1}}{x_{1}}

$x_{1}$ = 8

$x_{2}$ = 6

$y_{1}$ = 5

$y_{2}$ = 15

substituting into the formula , we have

m = $\frac{15-5}{6-8}$

m = $\frac{10}{-2}$

m = -5

Therefore the slope is -5

Whats 1/4 in a percent?

noname [10]

" 1 / 4 " means " 1 divided by 4 ".

Do that division, and you get " 0.25 " .

To change any number to percent, multiply the number by 100 .
The easy way to do that is to move the decimal point 2 places that way ==> .

When you multiply 0.25 by 100, you find that it's 25% .
