Answer: The y-intercept of this equation is 6.
Explanation: When doing slope intercept form, the formula is y = mx + b. "M" is slope, and "B" is y-intercept. In this equation, 4 is the slope and 6 is the y-intercept.
Solving the inequality, it is found that the correct interpretation of the solution is:
Reina's family can drive 83 more miles before they need to refill the gas tank.
The amount x of miles they can still travel is modeled by the following inequality:

To solve it, we treat it similarly to an equality, hence:


Hence:
Reina's family can drive 83 more miles before they need to refill the gas tank.
