Question

Can someone help, PLEASE?

Answer 1

Answer:

C. -3

Step-by-step explanation:

Start from (-1,4) drop down -6 spots then move over 2 spot to end up at (1,2). This is the same as writing -6/2 which equals -3.

If you start from other point (1,2) you'll have to move up 6 then back -2 to get to (-1,4) which is also -6/2 like above and slope is still -3.

Remember y = mx + b

m is the slope and with above example -6/2 top number is rise which move up/down and bottom number is run which move left/right.

Another way of solving it is:

(y2 - y1) / (x2 - x1)

4 - (-2) / -1 - 1

6 / -2

-3
