Aschool conducts 27 test in 36 weeks. assume the school conducts tests at a constant rate .what is the slope of the line that represents the number of tests on the y-axis and the time in weeks on the x- axis

 Slope of the line = 0.75.

Step-by-step explanation:

Since we have given that

Number of tests = 27

Number of weeks = 36

According to question,

Number of tests is on the y-axis and the time in weeks is on the x-axis.

So, the coordinates are the (0,27) and (36,0)

As we know the formula for "Slope of line":

Hence, Slope of the line = 0.75.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
