How do you identify the equation that matches a table?

Back

You can identify the equation by looking for a consistent pattern in the values of x and y, and then testing the equations to see which one fits the data.

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b, where m is the slope and b is the y-intercept.
