-2a-9=6a+15<br> Idk how to this equation could someone plzz consider helping me?

ollegr [7]

-2a-9=6a+15

Move 6a to the other side. Sign changs from +6a to -6a.

-2a-6a-9=6a-6a+15

-2a-6a-9=15

-8a-9=15

Move -9 to the other side. Sign changes from -9 to +9.

-8a-9+9=15+9

-8a=15+9

-8a=24

Divide both sides by -8

-8a/-8=24/-8

a=-3

Answer: a=-3

Find the slope between 2 points. <br> (16, 12) (40,18)

WITCHER [35]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

In this question, we have to find the slope with the given coordinates.

To find our slope, we would use the slope formula: $m = \frac{y2-y1}{x2-x1}$

Plug in your coordinates and solve:

$m = \frac{18-12}{40-16}\\\\m=\frac{6}{24}$

Simplify the fraction:

$m=\frac{1}{4}$

The slope would be $\frac{1}{4}$
