The y intercept occurs when x = 0. When x = 0 then y = 0 too and the y intercept is 0.
The inequality has to be pointing at 250 since that’s the maximum of money they can spend so B and D are out. If you did the math and solved it, the answer would be 7.5 and rounded up which is 8 hours.

Step-by-step explanation:
y + 4 = -4(x - 2) = -4x + 8
y - 4 = -4x
-4x - y = -4
4x + y = 4
Let x = the amount of film he started with on Wednesday
x + 3.75 - 0.28 - 1.3 + 1.25 - 2.7
x = 6.8
6.8 + 3.75 - 0.28 - 1.3 + 1.25 - 2.7 = 7.25
Dwayne has 7.25 hours of footage.
Hope that helps
