# Equations of Lines – Coordinate Geometry

**Equations of Lines – Coordinate Geometry (Question)**

Solve the following questions.

- If the gradient is 10 while the y-intercept is 9, what is the equation of the line?
- A straight line which gradient is 2 pass through the origin. What is the equation of the line?
- Form the equation of the line for two points (1,1) and (2,5) that fall within the line.

*Guide: *

*y = mx + c*

*Where, m is the gradient, while c refers to the y-intercept.*

**Equations of Lines – Coordinate Geometry (Answer)**

- y = 10x + 9
- y = 2x
- y = 4x – 3
