=====================================================

The equation of a line is a fundamental concept in mathematics, and it is often represented in the form of y = mx + c, where m is the gradient of the line, and c is the y-intercept. In this article, we will focus on understanding the gradient of a line, using the equation y = 6x + 8 as an example.

What is the Gradient of a Line?

The gradient of a line is a measure of how steep the line is. It is a numerical value that represents the rate of change of the line with respect to the x-axis. In other words, it tells us how much the y-coordinate changes when the x-coordinate changes by a certain amount. The gradient is denoted by the symbol 'm' in the equation y = mx + c.

Finding the Gradient from the Equation

To find the gradient of a line from its equation, we need to look at the coefficient of the x-term. In the equation y = 6x + 8, the coefficient of the x-term is 6. This means that for every unit increase in the x-coordinate, the y-coordinate increases by 6 units. Therefore, the gradient of the line is 6.
