Which of the following linear equations has a slope of -5/3? a. 3x + 4y - 5 = 0
b. 5x + 3y + 2 = 0
c. 2x - 5y = -3
d. 6y = 2x + 1
e. 3x + 5y + 4 = 0

i think it is 18

step-by-step explanation:

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

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

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

so, it becomes,

hence, first option 'a'   is correct.
