There are 18 students in Grade 7, 10 are in band, so 10/18 = 0.56 are in band.
There are 12 students in Grade 8, 10 are in band, so 10/12 = 0.83 are in band.
Students in Grade 8 are more likely to be members of the band.
Answer:
option: D.
Step-by-step explanation:
"The rate of change of two ordered pair is nothing but the slope of a line segment joining ordered pair (x,y)".
if a function is linear then it is represented as y=f(x)=ax+b
i.e. it is a line segment.
so the slope must be same if we consider any ordered pair.
Hence option D is correct i.e. She can check to see if the rate of change between the first two ordered pairs is same as the rate of change between the first and last ordered pairs.
