Slope and Intercept of Linear Equations
A linear equation of y in terms of x can be expressed by the
Example
Draw graphs of two equations by changing the slope or the y- intercept.
1. Graph the equations y = x and y = 2x.
2. Graph the equations y = x and y = 12 x.
3. Graph the equations y = x and y = - x.
4. Graph the equations y = x and y = x + 2.
Before There may be differences in the results of calculations and graph plotting depending on the setting. Starting Return all settings to the default value and delete all data.

GRAPH
The equation Y1 = x is dis- played first, followed by the equation Y2 = 2x. Notice how Y2 becomes steeper or climbs faster. Increase the size of the slope (m>1) to make the line steeper.
Notice how Y2 becomes less steep or climbs slower. De- crease the size of the slope (0<m<1) to make the line less steep.
