Understanding Linear Graphs and Gradients

What does a positive gradient indicate about the direction of a line on a graph?

• The line slopes downwards to the right.

• The line is vertical.

• The line is horizontal.

• The line slopes upwards to the right.

How is the gradient of a line calculated?

• By dividing the run by the rise.

• By adding the rise and run.

• By dividing the rise by the run.

• By multiplying the rise and run.

In the example given, what is the gradient of a line with a rise of 9 units and a run of 3 units?

• 1

• 3

• 9

• 6

If a car travels 10 meters horizontally and 2 meters vertically downwards, what is the gradient of the road?

• -2

• 2

• -0.2

• 0.2

Why is a negative sign used in the gradient calculation for a downward slope?

• To indicate the line is horizontal.

• To represent a fall instead of a rise.

• To make the calculation easier.

• To show the line is steeper.
