Is the function in the table linear or nonlinear and why?

x : -2, 0, 2, 4, 6

y : 5, 10, 15, 20, 25

a) the function is linear because the y-intercept is 0.

b) the function is linear because there is a constant rate of change.

c) the function is linear because all the y values are positive.

d) the function is not linear because there is a negative x value

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
