What is the equation of the line that passes through the point (3,-1) and is perpendicular to the equation y= -3x +2?

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.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
