Solve problems involving gradients of parallel and perpendicular lines (VCMNA338)

[/title][fusion_text]LO: To solve problems involving gradient of parallel and perpendicular lines
Know:

• What the gradient of a line
• How to calculate the gradient of a line
• What are parallel lines
• What are perpendicular lines

Understand:

• That the gradients of a line can determine whether a pair of lines are parallel or perpendicular.

Do:

• I can solve problems involving the gradient of parallel and perpendicular lines.

### Sometimes the slope (gradient) can go downwards towards the right, which makes the gradient (slope) negative.

### Sometimes the slope (gradient) can be very steep (2), and sometimes it can be small (1/2).

### A horizontal line has a gradient (slope)of 0 because the rise is always 0. Zero divided by any number is always 0, which makes the gradient of a horizontal line always 0.

### Parallel Lines have the SAME gradients.

### Perpendicular Lines have negative inverse gradients.
