Answer

a) linear

Explanation

There is a simple way to tell if a function is linear from a table: look at the x and y-values; if the y-values are increasing or decreasing by the same amount when their corresponding x-values increases or decreases by the same amount, you have a linear function; otherwise, you don't.

Look at the table

From 0 to 1 x is increasing by 1; from 8 to 10 (the corresponding values), y is increasing by 2

From 1 to 2 x is increasing by 1; from 10 to 12, y is increasing by 2

So, every time that x increases by 1, y increases by 2; therefore, we have a linear function.

Notice that form -2 to 0 x is increasing by 2; from 4 to 8 increasing by 4, which is the same rate as before (when x increases 1, y increases 1)

Explanation

When x increases by 1, y increases by 2; therefore we have a linear function.

If you look at the first and third tables,  y increases at different amounts every time x increases by 1; therefore, they are not linear functions.

In the first table when x increases by 1, y increases by 2, 4, or 10. Therefore, the table is not a linear function.

Similarly, in the third table when x increases by 1, y increases by 1, 3, or 5. Therefore, the table is not a linear function.

Answer

a) nonlinear

Explanation

A linear function is function of the form: or where is the independent variable and is the dependent variable.

In a linear function the coefficient of the variables is always 1.

Notice that the coefficient of the independent variable , in the function , is 2; therefore the function is nonlinear.

Answer

2=x3+y     Nonlinear

y+1=5(x−9)   Linear

7y + 2x = 12 Linear

4y = 24        Linear  

Explanation

2=x3+y The coefficient of the independent variable, x, is 3; therefore, the function is not linear.

y+1=5(x−9) We can simplify the expression to get:

y+1=5x-45

y=5x-46

Since y=5x-46 is in the form y=mx+b, we have a linear function.

7y + 2x = 12

Since 7y + 2x = 12 is a function of the form Ay + Bx = C, it is a linear function

4y = 24 We can siplify to get:

Since y=6 is a function of the form y = mx+b (with m=0), it is a linear function.

Answer

b) is not

Explanation

From 22 to 20, x decreases by 2; from 26 to 22, y decreases by 4. So, when x decreases by 2, y decreases by 4.

From 16 to 14, x decreases by 2; from 20 to 18, y decreases by 2. So, when x decreases by 2, y decreases by 2.

When x decreases by 2, y decreases by 4 or 2; therefore the function represented in the table is not a linear function.
