Answer:
The x-intercept of the line is 4 minutes.
That 4 minutes gives the time when Shari will reach her home.
Explanation:
The line 6x - 3y = 24......... (1), represents Shari's distance from home, y in blocks, on her run across town over time, x, in minutes.
So, at y = 0, from the above equation (1), we get 6x - 0 = 24, ⇒ x = 4.
Therefore, the x-intercept of the line (1) is 4 minutes.
That 4 minutes gives the time when Shari will reach her home and the distance between her and her home is zero blocks. (Answer)
