  1. 1. Linear Coordination- Finding the gradient
  2. 2. Contents <ul><li>What is a gradient </li></ul><ul><li>What is a positive and negative slope </li></ul><ul><li>Types of gradient </li></ul><ul><li>How to find the gradient </li></ul>
  3. 3. What is a gradient? <ul><li>A gradient is a slope of the line </li></ul>
  4. 4. What is a positive slope? <ul><li>A positive slope is a slope that shows a positive trend from left to right </li></ul>
  5. 5. What is a negative slope <ul><li>A negative slope is a slope that shows a negative trend from left to right </li></ul>
  6. 6. Types of gradients <ul><li>There are 3 types of gradients: </li></ul><ul><li>Where gradient is 0 </li></ul><ul><li>where the gradient is a positive or negative gradient </li></ul><ul><li>where the gradient is undefined. </li></ul>
  7. 7. Where gradient = 0
  8. 8. Postive or negative gradient
  9. 9. Undefined Gradient
  10. 10. How to find a gradient? <ul><li>Gradient works in this formula: </li></ul>
  11. 11. For example <ul><li>If you are given 2 points, (2,4) and (6,8) , this is a picture to show you: </li></ul>
  12. 12. <ul><li>To find the gradient, you take x2 – x1 and y2 – y1 </li></ul><ul><li>So, the gradient is 4/4 </li></ul>
