An 80-gallon tub drains at a constant rate of 5 gallons per minute. What is the y-intercept

Question

im doing my home work for the week and i really need this answer and i need to turn it in by 8:30 am tomorrow morning

Answer 1

y = 80 - 5x where y= number of gallons in the tub and x = minutes it's been drainiing

y intercept is graphically the point (0,80) or y=80 when you draw the line y=80-5x

when a linear equation is solved for y, the y intercept is the constant term
