**What we did in 2 hours:**

This lesson, we completed our **Maths EOY Revision **on **Linear Graphs**.

A few key points to take note for this topic:

1) **y = mx + c**, where m is the gradient of line and c is the y-intercept.

2) **Gradient** (steepness of line) = rise/run.

gradient of an *upslope* line = +ve number

gradient of a *downslope* line = -ve number

gradient of a *horizontal* line = 0

gradient of a *vertical *line is undefined.

3) **y-intercept** is where the line cuts the y-axis. Let x = 0 to find y-intercept.

4) **x-intercept **is where the line cuts the x-axis. Let y = 0 to find x-intercept.

5) If a **point** lies **on a line**, the x and y coordinate values of the point satisfy the equation of the line.

**What you received:**

Please take time to attempt the additional **Linear Graphs** questions available in the workbook. The solutions are available here: https://tinyurl.com/y6n54qmq

**Special Mention:**

**Lesson 40 **was brought forward to **15th September**. We had our revision on **Geometry **and** Number Pattern.**

We have finally wrapped up our Maths EOY Revision. Next lesson, we will have a** Maths mock test** – the Good Luck Paper on maths.

Till then, stay healthy and see you again soon! 🙂
