Answer:
Step-by-step explanation:
Y = 3x + 7....slope is 3, y int is 7
y = 3x + 2...slope is 3, y int is 2
when the slopes are the same, but the y intercepts different, then it is a parallel line with no solutions.
little tip :
slopes same, y int different, = no solution
slopes same, y int same = infinite solutions
slopes different, y int different = 1 solution

B can NOT represent y=5x because you are multiplying 5 by x not by y.
Answer: 
Explanation:
x = number of cups of yogurt
1.20x = cost of all the yogurt only
1.20x+2.50 = adding on the cost of milk
We set this expression to be less than or equal to 20.
In other words, the highest 1.20x+2.50 can go is 20 since $20 is her budget.
