Which equation best represents the line graphed above

Hi there!

The correct answer is option B

--------------------------------------------

Since x = -4 is a vertical line(perpendicular to horizontal), so there is no y-intercept and the slope is undefined.

"A vertical line has undefined slope because all points on the line have the same x-coordinate.

So, the slope is undefined and we also don't have the y - intercept.

Credit to my graphing calculator, it looks like this ↓↓

Best of luck with your studies!

UNO [17]

Answer:

336 ways ;

56 ways

Step-by-step explanation:

Number of ways to have the officers :

Number of qualified candidates, n = 8

Number of officer positions to be filled = 3

A.)

Using permutation (since the ordering matters):

nPr = n! ÷(n-r)!

8P3 = 8! ÷ (8-3)!

8P3 = 8! ÷ 5!

8P3 = (8*7*6)

8P3 = 336 ways

B.) Different ways of appointing committee: (ordering doesn't count as officers can also be appointed)

Using the combination relation :

nPr = n! ÷(n-r)!r!

8C3 = 8! ÷ (8-3)! 3!

8C3 = 8! ÷ 5!3!

8C3 = (8*7*6) ÷ (3*2*1)

8C3 = 336 / 6

8C3 = 56 ways
