The gradient (also called slope) of a line tells us how steep it is. To find the gradient: Divide the vertical change (how far it goes up or down) by the horizontal change (how far it moves …

Using the triangle drawn against the line you can verify that the gradient is given by the difference in the y values divided by the difference in the x values. Looking at the line you can easily …

One has a positive gradient and the other has a negative gradient. The product of their gradients is -1. The gradient is a measure of the slope of a line. It is the amount of vertical...

Here we will learn about straight line graphs including how to draw straight lines graphs of the form y = mx + c by using a table and from a pair of coordinates. We will learn how to calculate …

You can see the effect of different values of m (the slope) and b (the y intercept) at Explore the Straight Line Graph

Remembering positive or negative gradients. Line A is negative. Line B is positive. To remember this: Going from left to right. Push positively (+) Down Dash quickly (-) A graph is read from left …

We shall interpret the negative gradient later in this module. 3. Intercepts of a Straight Line . By putting x = 0 into the equation y = mx + c, the point where the straight line crosses the y axis is …

Gradient is another word for "slope". The higher the gradient of a graph at a point, the steeper the line is at that point. A negative gradient means that the line slopes downwards. The video …

ax + by + c = 0 is the defining equation of a straight line graph. The defining equation is written in the form y = mx + c where m is the gradient and c is the y-intercept. The domain of function a …

This is a negative gradient. The gradient can also be found by calculating the change in the \(y\) direction divided by the change in the \(x\) direction. The graph below shows how you could …
