Answer:
y = -6x + 70
Step-by-step explanation:
Since the amount of oil in the tank decreases constantly, we need to create a linear function. Using the base form, y = mx + b, we can replace -6 for m because volume decreases by 6 (or increases by -6) each hour, and +70 for b because we start off with 70 liters of oil. So we get y = -6x + 70, with x representing the number of hours, and y representing the volume of oil remaining.

Answer:
yes
Step-by-step explanation:
yes they are equivalent because when you reduce them they both equaly 1/2
Answer x=-4
This would make a straight line going perpendicular to y=-3 and would pass through the point -4,3.
3x+y=9.....i
3x-5y=15...ii
subtracting ii from i we get
6y=-6 so y=-1
x=10/3
