Answer:

m=-2

Step-by-step explanation:

plug in the points in the formula y2-y1/x2-x1

I suggest getting m a t h w a y its a website and app thats useful.. and good.. and I like it

answer

-2

explanation

the slope can be found through m = (y2 - y1) / (x2 - x1)

with the points (-5, -2) and (-1, -10)

x1 = -5

x2 = -1

y1 = -2

y2 = -10

m = (-10 - -2) / (-1 - -5)

m = -8 / 4

m = -2

Help!! Lots of points

$\frac{ {5}^{2} }{ {2}^{2} } = {( \frac{5}{2}) }^{2}$
Since they are both squared.

Evaluating 5^2 and 2^2 and finding the quotient also works.

$\frac{ {5}^{2} }{ {2}^{2} } = \frac{5 \times 5}{2 \times 2} = \frac{25}{4} = 6.25\\ \frac{ {5}^{2} }{ {2}^{2} } = {( \frac{5}{2} )}^{2} = 2.5 \times 2.5 = 6.25$
The third option, "Evaluate 5^2 and 2^2 ...," and the last option, "Rewrite the expression as (5/2)^2 ...," are the correct choices.

Ghella [55]

<u>Answer:</u>

The length of a paper clip chain is directly proportional to the number of paper clips. If a chain with 65 paper clips has a length of 97.5 inches then the length of chain with 14 paper clips is 21 inches.

<u>Solution:</u>

Given that the length of a paper clip chain is directly proportional to the number of paper clips. Directly propotional means when the length of paper clip increases, then the number of paper clips also increases in same ratio.

Hence, by above definition, we get

$\frac{l_{1}}{l_{2}} = \frac{n_{1}}{n_{2}}$ ------- eqn 1
