Answer:

To find m ( slope) we'll use the Slope Formula:

$\boxed{\sf{Slope\:(m)}=\cfrac{y_2-y_1}{x_2-x_1}}$

<u>Subtract the numbers:-</u>

$\sf 7. \:m=\cfrac{4-2}{6-5} =\boxed{2}$

_______________

$\sf 8.\: m=\cfrac{-1-3}{2-6} =\boxed{1}$

_______________

$\sf 9.\: m=\cfrac{-4-(-2)}{3-1} =\boxed{-1}$

_______________

$\sf 10.\: m=\cfrac{0-3}{0-(-3)} =\boxed{-1}$

_______________

$\sf 11.\:m=\cfrac{4-2}{3-1} =\boxed{1}$

_______________

$\sf 12.\: m=\cfrac{1-7}{2-5} =\boxed{2}$

_______________

$\sf 13.\:m=\cfrac{11-9}{1-(-4)} =\boxed{\frac{2}{5}}$

_______________

$\sf 14.\:m=\cfrac{2-3}{3-5} =\boxed{\frac{1}{2}}$

_______________

$\sf 15.\: m=\cfrac{11-5}{2-9} =\boxed{-\frac{6}{7}}$

_______________

$\sf 16.\: m=\cfrac{-7-\left(-6\right)}{8-13}=\boxed{\frac{1}{5}}$

_______________

$\sf 17.\: m=\cfrac{4-4}{6-1} =\boxed{0}$

_______________

$\sf 18. \: m=\cfrac{2-(-7)}{5-5}=$

↑ Undefined

If EF=6 and EG=21, find the value of FG. The drawing is not to scale.

pantera1 [17]

You can find the value of FG by subtracting the value of EF from EG.

EG - EF = FG
21 - 6 = FG
15 = FG

The value of FG is B. 15 .

Make a conjecture about the next item in the sequence 1, -4, 9, -16

Snezhnost [94]

To get -4 from 1, we must either subtract 5 from 1 or mult. 1 by -4. Unfortunately subtracting 5 from -4 does not result in 9, and mult -4 by -4 does not result in -16. So neither "works" in predicting the next term.

Can you think of any other experiments to do that would help you discover the pattern 1, -4, 9, -16?

Miss hit travel 21120 ft how many miles did she travel

Sunny_sXe [5.5K]

4 miles because there are 5280 ft in one mile so if you were to multiply that by 4 you would get 21120 ft
