5.3 Intercepts

1. The x-intercept is the point of intersection of a straight line with the x-axis.

2. The y-intercept is the point of intersection of a straight line with the y-axis.

3. In the above diagram, the x-intercept of the straight line PQ is 6 and the y-intercept of PQ is 5.

4. If the x-intercept and y-intercept of a straight line are given,

Gradient, m = - \frac{y - intercept}{x - intercept}
