All straight line graphs have an equation that can be written in the form 𝑦 equals 𝑚𝑥 add 𝑐, where 𝑚, the coefficient of the 𝑥 term, is the gradient or slope of the line. The constant, 𝑐, is ...

👉 Learn how to find the slope between two points. The slope of a line is the steepness of the line. The horizontal line has ...

The gradient tells us how steep a line is, therefore the bigger the gradient the steeper the line is. A positive gradient is a straight line which slopes up to the right. A negative gradient is a ...
