What is the slope of the line through (2,-2)(2,−2)

0. the line is not determine because both points have the same coordinates.

Step-by-step explanation:

m = (y-y)/(x-x)

m = (- 2 - -2)/(2 - 2)

m = (- 2 + 2)/(2- 2)

m = 0

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.
