Answer:
y-intercept: (0, -1.2)
Step-by-step explanation:
Let, the number of weeks = x
It would be: 17 + 11x ≥ 72
Subtract 17 from both sides,
11x ≥ 55
Divide by 11,
x ≥ 5
So, at-least he needs 5 weeks for that
Hope this helps!

There's no division by zero, so x can't be a value which x - 6 = 0
x - 6 ≠ 0
x ≠ 6
