A9c – Finding the equation of a line through two given points or through one point with a given gradient

This is the students’ version of the page. Log in above for the teachers’ version.

Skill isolation: Finding the equation of a line with given gradient and y-intercept

Skill isolation: Finding the gradient of a through two points

Use this applet to practise finding the gradient of a line through two points. Click the dashed line segments to help you, or click “Show gradient” to reveal the answer. You can then try finding the gradient of a new line by clicking the “New line” button or by moving the red points around. You can also use your mouse’s scroll function or pinch to zoom in or out.
