Coordinate Plane Table Graph Linear Equations

What is slope-intercept form?

• The x-coordinate of the point where the graph of a line crosses the x-axis.

• A linear equation written in the form y = mx + b where m = slope and b = y-intercept.

• An equation between two variables that creates a line when plotted on the coordinate plane.

• The y-coordinate of the point where the graph of a line crosses the y-axis.
