Find the slope of the line that passes through ( 5, -4) and (9, -4 ). Step 1: Label the points:
First point: (
x1 , y1) =
Second point: ( x2 , y2) =

Step 2: Write the formula: and Substitute the numbers:
Slope m = y2 - y1x2 - x1
Step 3: Simplify:

Slope m =

(round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
