Can you guys help me find the slope for the given graph and y-intercept
(pictures included)

The volume of a cube is 8 in to the 3rd power. how long is each side?

What is the upper quartile in the box plot?

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.
