(-12,16) and (-4,-2)find the slope

It's -9/4 or -2 1/4. please mark me brainliest <3

Step-by-step explanation:

1) label x1, y1, x2, and y2.

x1     y1       x2 y2

(-12, 16)     (-4,-2)

2) Remember the formula is y2-y1

                                                x2-x1

3) substitute

-2-16

-4-(-12)

4) two minuses (negatives) is a positive (+)

so,

-2-16             -18

=      

-4+12               8

5) simplify

-18 divided by 2          -9

                         =      or -2 1/4

  8 divided by 2             4

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
