16. Write the equation for a line with a y-intercept of 3 that also passes through the point (2,5). y= x +3

17. y = 3x + 2 y = 3x – 2 Look at the 2 equations above. Choose the statement that best fits the comparison of the two equations. a) The items have different y-intercepts and different rates of change. b) The rates of change are the same, but the y-intercepts are different. c) The items have the same y-intercepts and the same rate of change. d) The y-intercepts are the same, but the rates of change are different. b
