Answer: Intercept of the equation = (9,0)

Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)

Step-by-step explanation:

Given: When t= the number of hours since Lauren left her house, the charge remaining in Lauren's battery, as a percentage, can be modeled by the equation B=63-7t .

To find the x-intercept, put B =0  (as x denoted the independent variable , here independent variable is 't')

Hence, the x-intercept of the equation = (9,0)

i.e. Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)
