Question

Introduction to Linear Functions: Which table represents a linear function?

Answer 1

Answer:

The table in the top right

Step-by-step explanation:

That table represents the equation y=-2x-1. It is the only table that represents a linear equation.

To be a linear equation it has to consistently add the same amount up and right OR down and right (depending on if it's a positive or negative equation)

I have included a picture of the graph with the equation and all points on it (click/tap on it to see the full picture.)

Answer 2

The table which represents a linear function is one on the top-right corner.

What is linear function?

A linear function is a mathematical relation which is characterized by a constant slope otherwise known as the rate of change of the function.

Upon evaluation of the slope of each table; only the top-right corner table has a constant slope.

• slope, m = (-5-(-3))/(2-1)

• m = -2/1 = -2.

Ultimately, a linear function is characterized by a constant slope as observed in the top-right corner table in discuss.
