1. In each case, which average do you think is most useful: the mean, median, or mode? Justify your answer.

Find the value of the variable and the length of each secant segment.

Aline has a slope of and a y-intercept of –2. what is the x-intercept of the line?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
