Myra uses an inverse variation function to model the data for the ordered pairs below. (2, 30), (3, 20), (4, 15), (5, 12), (6, 10) which statement best explains whether an inverse variation function is the best model for the data?
an inverse function is the best model because as x increases, y decreases. an inverse function is the best model because the products of corresponding x- and y-values are equal. an inverse variation function is not the best model because data points are closer to forming a straight line.
an inverse variation function is not the best model because the data points show an exponential decay.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
