Answer:
sorry for being super late....
Explanation:
For the first one it is x= -5y
And the graphing point would be at positive 5 on the x axis and on the other side of the x axis it will be -5.
For the second one it is ( 111/2, −21/2 )
And in equation form it is x = 111/2, y = −21/2
The graphing point for this one is x = 55.5, y = -10.5
For the third one it is B because the cost of River Y is 33 and River Z tells you basically what you need to have and that is 3n + 15, and in the question it says "River Z costs $3 per hour plus a $15 deposit" and cost is the c so that is the answer for the third one.
And last but not least the fourth one.... the answer is (-4,5) which as an equation is x = -4, y = 5, and the points is are literallyiterally (-4,5).
I hope this helps you out later on when you see problems like this and again this is so late but I saw it so I decided to answer it for you, and have an awesome day!!!!!!!!
