If a line pass through three points, they are collinear points, and the determinant of a matrix produced by their coordinates equals 0.

Knowing this, we can fin the value of n.

We need a triangular matrix, so we can complete it with 1's.

\left[\begin{array}{ccc}6&3&1\\8&4&1\\n&-2&1\end{array}\right]

24 + 3n - 16 - 4n + 12 - 24 = 0

- n - 4 = 0

- n = 4

n = -4

The value of n it's -4.

Hope it helps.

Reword this plz The average test score for the science class after completing test 2 is 84.
eduard

Answer:

Given : The linear function f(x) = 0.2x + 79 represents the average test score in math class, where x is the number of the test taken.

The linear function g(x) represents the average test score in your science class, where x is the number of the test taken.

To Find : test average for math class after completing test 2

test average for science class after completing test 2

Which class had a higher average after

completing test

Solution:

f(x) = 0.2x + 79

=> f/2) = 0.212) + 79 = 79.4f(x) = 0.2x + 79

=> f(4) = 0.2(4) + 79 = 79.8

test average for math class after completing test 4 = 79.8 =

1 1 2 3 4 g(x) 86 84 82 80

Х

g(2) = 84

test average for science class after completing test 2 = 84

g(4) = 80

test average for science class after completing test 4 = 80

80 > 79.8science class has more average than
