Input Output Tables Linear Equations

Is function represented by the table linear or nonlinear?

• linear

• nonlinear

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

The table shows the cost of a pizza, P(t), based on the number of toppings, t. Write a linear function for P(t).

• P(t) = 3t + 17.5

• P(t) = 2t +11.5

• P(t) = 3.5t + 9

• P(t) = 2.5t + 10

Given the table, write the equation in the slope-intercept form.

• y = 1/3x + 6

• y = 3x + 6

• y = 2x + 6

• y = 1/2x + 6

What equation does the table represent?

• y=x+1

• y=x-1

• y=2x+1

• y=2x-1

• A/F

• B/G

• C/H

• D/J
