What is the slope of a line?
The slope of a line is also sometimes called the gradient of a line.
Answer: The slope of a line is the ratio of change in y-coordinate to change in x-coordinate of that line.
Let us learn more about the slope of a line.
The slope of a line is nothing but the change in the y coordinate with respect to the change in the x coordinate of that line. It is denoted by m.
m = Δy / Δx
The slope of a line is also defined as the measure of the tangent of the angle made by the line with the x-axis.
m = tanθ = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.
The slope is constant throughout a straight line. A line can be positive slope, negative slope, zero slope, and undefined Slope.
