10. False. Erica's equation (y = -0.5x) will pass through the origin, but Aliyah's equation (y = 2.5x - 8) will not pass through the origin.
11. True. Erica's equation (y = -0.5x) is proportional because it can be written in the form y = kx, where k = -0.5.
12. False. Erica's equation (y = -0.5x) has a negative slope, but Aliyah's equation (y = 2.5x - 8) has a positive slope.
Two students wrote the equations shown below. True or false
