(-1,2) and (-4,8) Find the slope of the line that contains the point
1. 2
2. 6/5
3. -2
4. -6/5

-2

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 8 -2)/(-4- -1)

   = (8-2)/(-4+1)

   = 6/-3

   = -2

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
