Linear or non linear

Answer:

Linear equation.

Explanation:

It is linear as y increases 11 grids with every increase in x grid.

OR,

I will make a linear equation from two coordinates: (1,11),(2,22)

slope: → →

the find equation using:

y - y1 = m(x - x1) → y - 11 = 11(x-1) → y = 11x ....this is linear equation.

Therefore it's linear.

OR,

Then check if 3rd and 4th coordinate matches the equation.

y = 11x                                                      y = 11x

y = 11(3)                                                    y = 11(4)

y = 33 ...therefore matches                    y = 44...therefore matches

So, its a linear equation.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

step-by-step explanation:

mean or average is 40.6
