Below are the equations that use the variable x, where x is any real number.
1. y = x
2. y = 2x
3. y = 3x
4. y = 4x
1. For each equation, make a table to find the coordinates of three points.
2. Graph each equation on the same x - y plane (use ordered pairs in number 1). Label each graph with its equation.
3. The equation can be described by the equation y = ax. Give the values of a.
4. How does the value of a affect the graph?​
