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 .

Compare the equations y=3x and y=x of the graph

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

has a slope of 3 instead of 1. 

Compare the equations y=3x and y=x of the graph

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

has a slope of 3 instead of 1.
