Given two points M & N on the coordinate plane, find the slope of MN , and state the slope of the line perpendicular to MN .

telo118 [61]

Answer:

Problem 1) $m = \dfrac{1}{4}$ $slope_{perpendicular} = -4$

Problem 2) $m = \dfrac{1}{3}$ $slope_{perpendicular} = -3$

Step-by-step explanation:

$slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$slope_{perpendicular} = \dfrac{-1}{m}$

Problem 1) M(9,6), N(1,4)

$slope = m = \dfrac{6 - 4}{9 - 1} = \dfrac{2}{8} = \dfrac{1}{4}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{4}} = -4$

Problem 2) M(-2,2), N(4,-4)

$slope = m = \dfrac{4 - 2}{4 - (-2)} = \dfrac{2}{6} = \dfrac{1}{3}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{3}} = -3$

Anna71 [15]

Answer:

4 touchdowns per game.

Step-by-step explanation:

Given:

And a high school teachers 256 touchdowns made last year if 64 games are played.

Question asked:

What is the mean or the average number of touchdowns made per game ?

Solution:

Touchdowns made = 256

Number of games played = 64

We have to find mean or average:-

$Mean = \frac{Sum\ of\ observations}{number\ of\ observations}$

$\frac{256}{64} =4$

Therefore, a high school teachers made 4 touchdowns per game.
