Awater truck is filling a swimming pool. the equation that represents this
relationship is y = 19.75x where y is the number of gallons of water in the pool and
x is the number of minutes the truck has been filling the pool.
choose true or false for each statement.
a.
the unit rate for this relationship is 1 gallon per 19.75 minutes.
true
true
false
false
b.
this is a proportional relationship because the graph of the
equation is a straight line through the origin.
true
false
c. the water in the swimming pool increases by about 100 gallons
every 5 minutes.
true
false
d.
a table of related x-and y-values for this relationship would
show equivalent ratios.
true
false
e. the point (8, 150) could be a point on this graph.

  a. false

  b. true

  c. true

  d. true

  e. false

Step-by-step explanation:

a. False. The "unit rate" is 19.75 gallons per minute. The "unit" of a "unit rate" is in the denominator. Here, the denominator of the rate is 1 minute.

__

b. True. A graph of a proportional relationship is a straight line through the origin.

__

c. True. In 5 minutes, the water in the pool will increase by 98.75 gallons, about 100 gallons.

__

d. True. The ratio of a y-value to an x-value will always be 19.75. That is the meaning of this proportional relationship.

__

e. False. The points (8, 158) or (7.5949, 150) will be on the graph. The point (8, 150) will not.
