Answer:

Step-by-step explanation:

Given that there are 8 candidates for student government: Hal, Mary, Ann, Frank, Beth, John, Emily, and Tom.

The three candidates that receive the highest number of votes become candidates for a runoff election.

i.e. 3 persons out of 8 to be selected for becoming candidates for a runoff election.

Since order does not matter we use combinations here

3 persons out of 8 can be done in 8C3 ways

= 56

no of 3-candidate combinations possible are 56

What is the slope of (-3,2) and (6,1)

evablogger [386]

Answer: -1/9

Step-by-step explanation:

Find the Slope (−3, 2) and (6, 1)

Slope is equal to the change in y over the change in x, or rise over run.

$m=\frac{change in y}{change in x}$

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

$m = \frac{y_2-y_1}{x_2-x_1}$

Substitute in the values of x and y into the equation to find the slope.

$m = \frac{1-(2)}{6-(-3)}$

Simplify the numerator. Tap for more steps...

$m=\frac{-1}{6-(-3)}$

Simplify the denominator.

$m=-\frac{1}{9}$
