Match the red line with lines a) to i) by changing the values of [math]m[/math] and [math]c[/math]. [br][i][br](What features of the red line do you think [math]m[/math] and [math]c[/math] represent?)[br][br][i](Be sure to record your responses in Problem Set 2)[/i][/i]

Match your red line with at least two random lines.[br][br][i][i](Be sure to record your responses in Problem Set 2)[/i][/i]

The gradient of a line is denoted by the symbol[size=100][size=150] [math]m[/math] [/size][/size]in the straight line equation [math]y=mx+c[/math]. [br][br]The definition of a gradient is: “[i]Change in vertical distance [math](y)[/math] [/i][i]as the horizontal distance [math](x)[/math] [/i][i]increases by 1 unit”.[br][br][/i]Or alternatively, the following formula may be used: [math]m=\frac{rise}{run}[/math] .[br][i][br]Move the slider for [math]m[/math] to see different slope patterns.[br][br](What value does [/i][math]c[/math][i] represent?)[/i]
