Graphing

Plot a point at the origin, then "walk off" the rise and run to find the next point. You are now graphing the line with equation...

y = -3x

Multiple Choice

Which table did you discover matched this equation?

$$y\ =\ \frac{1}{2}x$$

What is an important takeaway you want to remember about slope?

• Slope is "Rate of Change"

• m stands for "slope"

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

Multiple Choice

Which equation matches the table shown? Use your worksheet to figure it out (you should already have this answer ready).

• $$y\ =\ 2x$$
