Question

which function can be used to find y, the number of gallons of fuel remaining in the tank of the semi truck after it traveled x miles?a.) y= -1/10x + 240b.) y= -1/6x + 240c.) y=240x - 30d.) y = 240x - 10

Answer 1

The line passes through point (0,240) and (300,210).

Determine the equation of line passing through point (0,240) and (300,210).

`\begin{gathered} y-240=(210-240)/(300-0)(x-0) \\ y-240=-(30)/(300)x \\ y=-(1)/(10)x+240 \end{gathered}`

So the number of gallons of fuel remaining in the tank after x km is y = -1/10x + 240.
