A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
Answer:
11,880 different ways.
Step-by-step explanation:
We have been given that from a pool of 12 candidates, the offices of president, vice-president, secretary, and treasurer will be filled. We are asked to find the number of ways in which the offices can be filled.
We will use permutations for solve our given problem.
, where,
n = Number of total items,
r = Items being chosen at a time.
For our given scenario
and
.





Therefore, offices can be filled in 11,880 different ways.
