A student in a foreign language program learns 15 new words each week. Which graph best represents the relationship between x, the number of weeks the student has been in the program and y, the total number of new words the student has learned?
What is the Constant of Proportionality for the table below? _________
(Hint: Just find the unit rate - Cost per lb.)
$10 per lb.
$15 per lb.
$1.50 per lb.
$1.75 per lb
What is the equation (Cost per lb.) for this chart?
c = 10w
w = 1.50c
c = 15w
$0.08 per pack
$0.80 per pack
$1.80 per pack
What is the COP (Unit Rate) of this graph? (Hint: Remember - the xy pair when x=1 , y is the unit rate)
1.25 gallons per minute
2.5 gallons per minute
5 gallons per minute
What is the cost per guest and the equation that goes with this graph?
$2 per guest so equation is y = 2x
$4 per guest so equation is y = 4x
$10 per guest so equation is y = 10x
What is the equation of this graph?
y = 2x
y = 4x
y = 8x
Remember:
