PLZ HELP 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 6
fraction 24 over 30
fraction 30over 24
fraction 6 over 30

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

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
