What is x > 6
300
mean
What is the sum of the data values divided by the number of data values
300
Quartile 2
What is the median- the middle number of the data
300
The equation of the line that has a slope of 2 and passes through the point (3,-1)
What is y = 2x - 7
300
is this a function? {(0,2), (-2,2), (1,4), (4,1), (0,-1)}
