How do you calculate gradient GCSE?
To determine the gradient of a line:
- choose any two points on the line.
- draw a right-angled triangle from one to the other, using the line as the hypotenuse.
- determine the height and width of the triangle.
- gradient = height ÷ width.
What does the gradient represent GCSE maths?
Gradient is a measure of steepness. As you move along a line from left to right, you might go up, you might go down or you might not change at all. Gradients can be: positive – going up.
What is a gradient of 6?
Slopes vs. gradients vs. % grades
| Slope | ||
|---|---|---|
| Angle (degrees) | Gradient | Grade (%) |
| 5 | 1 | 8.75 |
| 5.74 | 1 | 10 |
| 6 | 1 | 10.5 |
Is Y MX B or C?
The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis.

How are gradients and graphs used in math?
Gradients and Graphs. 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 below is a tutorial on Gradients. Finding the gradient of a straight-line graph It is often useful or necessary to find out what the gradient of a graph is.
How to calculate the gradient of a line?
If two lines are perpendicular, then their gradients will multiply together to give -1. Find the equation of a line perpendicular to y = 3 – 5x. This line has gradient -5. A perpendicular line will have to have a gradient of 1/5, because then (-5) × (1/5) = -1. Any line with gradient 1/5 will be perpendicular to our line, for example, y = (1/5)x.
Why are two lines with a gradient of 2 parallel?
The lines y = 2x + 1 and y = 2x + 3 are parallel, because both have a gradient of 2. Perpendicular Lines (HIGHER TIER) Two lines are perpendicular if one is at right angles to another- in other words, if the two lines cross and the angle between the lines is 90 degrees.
