The slope-intercept form is a method used to represent the equation of a straight line in the coordinate plane. The slope-intercept form of a linear equation is where one side contains just "y" and is represented in the form of y=mx+b, where "m" and "b" are numbers. The slope, "m," represents the steepness of a line, while the y-intercept, "b," represents the y-coordinate of the point where the graph of the line intersects the y-axis. The slope-intercept form is called so because it gives two main features of the line it represents: the slope and the y-intercept. The slope is the number in front of x, and the y-intercept is the constant term in the equation. The slope-intercept form is useful because it gives a clear picture of the lines slope and y-intercept, making it easy to graph the line.
