How to work out the gradient of a straight line - BBC Bitesize.
Where m is the slope (gradient) of the line and c is the y-intercept. To obtain the gradient, find two points upon the line. For the sake of this example, let's assume that the two points are (1,3) and (0,1). The gradient can be calculated by taking the difference in the y-coordinates and dividing by the difference in the x-coordinates.
Slope intercept vs Point Slope Form. There are a few different ways to find the equation of line from 2 points. The first half of this page will focus on writing the equation in slope intercept form like example 1 below. However, if you are comfortable using the point slope form of a line, then skip to the second part of this page because writing the equation from 2 points is easier with.
Unit 5 Section 2: Straight Line Graphs. We look in this section at how to calculate coordinates and plot straight line graphs. We also look at the gradient and intercept of a straight line and the equation of a straight line. The gradient of a line is a measure of its steepness. The intercept of a line is the value where the line crosses the y.
Point-slope form of a line is one method to write the equation of a line. Start with the slope equation, which is basically the difference between two points, and then rearrange the terms to obtain the point-slope form of a line. The point-slope form of a line provides a formula that is useful in finding the slope of a line from an equation and a point the line passes through. The point-slope.
