Gradients of straight-line graphs
•The gradient of a line is a measure of how steep the line is.•The gradient of a line can be positive, negative or zero if, moving from left to right, we have
y
x
a horizontal line
Zero gradient
y
x
a downwards slope
Negative gradient
y
x
an upwards slope
Positive gradient
•If a line is vertical its gradient cannot by specified.

x2 – x1
y2 – y1
the gradient =y2 – y1
x2 – x1
Finding the gradienty
