Find the slope of the line that passes through each pair of points 1. (4, 3), (-1, 6)

2. (2, 2), (-2, -2)

3. (-3, 2), (7, 2)

4. (-8, 6), (-8, 4)

PLEASE HELP MEEE

1. -3/5

2. 1

3. 0

4. undefined

Step-by-step explanation:

slope equals y2 - y1 over x2 - x1

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

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%
