What is a linear equation?

Back

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

What does the slope of a linear equation represent?

Back

The slope represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is.

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

How can you determine if a point lies on the line represented by a linear equation?

Back

Substitute the x value of the point into the equation and see if the resulting y value matches the y value of the point.

What does it mean for two graphs to represent the same linear equation?

Back

Two graphs represent the same linear equation if they have the same slope and y-intercept, meaning they lie on top of each other.

What is the significance of the x-axis and y-axis in graphing?

Back

The x-axis represents the independent variable (x values), while the y-axis represents the dependent variable (y values) in a graph.
