If they don't intersect then there is no solution and the lines are parrell.
The answer is D. In an ordered pair, the x-value, which tells you to move left or right, comes first, followed by the y-value, which tells you to move up or down.
To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.
This means to fill 50 gallons, you will need 50 groups of 30 seconds.
50 x 30 = 1500 seconds
1500/60 = 25 minutes.
It will take 25 minutes.
You could also think of it as filling 2 gallons every minute. It would take 25 of these.
Answer:
y = -3/4x - 2
Step-by-step explanation:
y = -3/4x + b
1 = (-3/4) × -4 + b
1 = 3 + b
-2 = b
b = -2
y = -3/4x -2
