**y = mx + c**

**This refers to the point where the line cuts the y-axis. For x = 0 ; the equation becomes y = m(0) + c therefore y = c ; meaning where x = 0 ,**

__y-intercept__*the line cuts the y-axis at the value of c,......... c = y-intercept*

__This refers to : 1) how steep the line is 2) the direction on the line the slope is defined by__

**Slope***m =*

*defining the slope ........................m = slope*Play with different values for m and c by using the slides marked "m" and "c" in the graph above , and note the effects on the y-intrecept and the slope.
