Question

1. what is the difference between a linear and nonlinear graph?
2. why do we use a best-fit line on a graph?

Explanation:

Define linear and nonlinear graphs

A linear graph forms a straight line, showing a constant rate of change. A nonlinear graph is curved, showing a changing rate. This relates to Linear and Nonlinear Relationships.

Explain the purpose of a best-fit line

A best-fit line shows the general trend of data points. It helps us make predictions. This relates to Line of Best Fit.

Answer:

Question 4

A linear graph forms a straight line, while a nonlinear graph is curved.

Question 5

A best-fit line is used to show the general trend of data and make predictions.
