First question, answer is A, the starting point in the graph shows it’s (0,150) while the slope is 30, look at the labeled axis.
second question, i have to do work for it, i can answer it later. remind me. but in order to find the slope, the formula is delta y over delta x. then to find the y intercept, do what’s called “collect the evidence”. this is when you fill out all needed info, it will look like this- y= x= m= b= ??
idk ab the third question, they would all make the function fine?? idk i’m confused, it doesn’t make sense
fourth question, the answer would be B
when a=4 and b=3,
3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8

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.
