The graph shows the number of sprays an automatic air freshener dispenses, y, in x minutes

Which expression can be used to calculate the rate per minute at which the air freshener dispenses sprays?
fraction 30 over 2
fraction 2 over 30
fraction 30 over 8
fraction 8 over 30

Answer 1

the first dot is on 2 for number of sprays and 30 for time

so the expression would be number of sprays over time so 2 over 30

2/30 that would reduce to 1/15 meaning each spray happens every 15 minutes

Answer 2

In this exercise we have to interpret the reported graph of an increasing linear function, we find that:

Letter B

Recalling the concepts of an increasing linear function as:

• Linear functions happen those whose diagram is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function bear individual independent changing and individual dependent changeable. The independent changeable is x and the helpless changing happen y.

With this explanation we have:

Expression would be number of sprays over time so 2 over 30, will be equal to:

$30/2=15$
