Find an equation for the line that passes through the points (5,-3) and (-1,-1)

y = -1/3x - 4/3

Step-by-step explanation:

y = mx + b

m = (y' -y) / (x'-x) = (-1 - (-3)) / (-1 -5) =  2 / -6 = - 1/3

b = -3 - (-1/3) × 5 = -3 + 5/3 = -4/3

check : b= -1 - (-1/3) ×(-1) = - 4/3

y = -1/3x - 4/3

sine

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.
