Graphing

Graph the equation

y = 2x

Remember that it should go through the origin.

Hint: $$slope\ =\ m\ =\ \frac{rise}{run}\ =\ \frac{2}{1}$$

Graphing

Graph the equation

$$y\ =\ \frac{2}{3}x$$

Remember that it should go through the origin. , and the point (6,4)

Hint: $$slope\ =\ m\ =\ \frac{rise}{run}\ =\ \frac{2}{3}$$

Graphing

Graph the equation

$$y\ =\ -3x$$

Remember that it should go through the origin. , and the point (1,-3)

Hint: $$slope\ =\ m\ =\ \frac{rise}{run}\ =\ -\frac{3}{1}$$

Graphing

Graph the equation

$$y\ =\ 4x$$

Remember that it should go through the origin. , and the point (1,4)

Hint: $$slope\ =\ m\ =\ \frac{rise}{run}\ =\ \frac{4}{1}$$

Multiple Choice

Slash the trash and select the graph that matches the equation:

$$y\ =\ \frac{1}{3}x$$

Hint: The slope is positive...which graph can you eliminate? Our graph will go through the origin...can we eliminate another graph?

There are 2 left to consider. Which ahs a rise of 1 and a run of 3?

Multiple Choice

Slash the trash and select the graph that matches the equation:

$$y\ =\ 3x$$

Hint: The slope is positive...which graph can you eliminate? Our graph will go through the origin...can we eliminate another graph?

There are 2 left to consider. Which ahs a rise of 3 and a run of 1 (slope of 3/1)?

Multiple Choice

HINT: Remember the equation y = mx ... the mx means "Slope times x"

The table below shows the relationship between the number of Girl Scout Cookie boxes purchased and the total cost in dollars. The cookies cost $6 per box.

The total cost of the cookies purchased, y, is equal to....

• The number of boxes purchased, x

• The number of boxes purchased, x, plus $6

• The number of boxes purchased, x, times $6

• The number of boxes purchased, x, divided by $6

Multiple Choice

Remember: y = mx ... what does that mean?

The table below shows the relationship between the number of chicken wings purchased and the total cost in dollars. The wings cost $2 per piece.

The total cost of the chicken wings purchased, y, is equal to....

• The number of wings purchased, x

• The number of wings purchased, x, plus $2

• The number of wings purchased, x, times $2

• The number of wings purchased, x, divided by $2
