Practice on your own how to find the equation of a straight line given the graph of a straight line. Learn how to learn on your own. The equation of a straight line using the gradient (or slope) intercept form is y = m x + c where m is the gradient or slope and c is the y intercept value.
1. Can you find m, the gradient (slope) of the line 2. What is the y intercept value c? 3. Form the equation of the line y = m x + c, then type it into the input box Repeat this applet at least 10 times to be sure you have learnt how to find the equation of a straight line given a graph! Happy learning how to build up habit of doing self directed learning!
