10. which of the following is a linear equation? a. 4x² +9y2 = 25b. 2+ 6 = 15c. 2x-3y=7d. 4x+6 = 30

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.
