John reads an equal number of pages of a book every week. the graph below shows the number of pages of the book left to read, y, after x weeks:
which equation best models the relationship between x and y?
y = −5x + 25
y = −25x + 125
y = −25x + 175
y = −5x + 125

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
