Which of the following lines goes through the point (0, 4) and is parallel to y = 5x - 3?
y = 1/5x - 3
y= 5x - 7
y = 5x + 4
y = -5x - 3
Which system best represents the situation?
4x + 7y = 578

At a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for 2 tacos and 3 small glasses of milk is $5.15. Write a linear system to model this situation.
t + m = 2.10
3t + 2m = 5.15
t + m = 2.10
2t + 3m = 5.15
3t + 2m = 2.10
t + m = 5.15
2t + 3m = 2.10
t + m = 5.15
