Graph by Making a Table:

The equation is .

Make a table; choose some values for x and find the corresponding values for y.

 x y = 3x y (x, y) – 2 = 3(– 2)= – 6 –6 (– 2, –6) – 1 = 3(– 1)= – 3 – 3 (– 1, – 3) 0 = 3(0) =     0 0 (0, 0) 1 = 3(1) =     3 3 (1, 3) 2 = 3(2) =     6 6 (2, 6)

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.

4.Draw a line .

The graph of and both have a y-intercept of 0, but the graph of

has a slope of 3 instead of 1.

The graph of and both have a y-intercept of 0, but the graph of
