What is the equation of the line in standard form, which has a slope of ― 2 5 and a y-intercept of 10? (MAFS.912.A- CED.1.2) A. 2 ― 5 = 50 B. 50 ― 5 = 2 C. 50 + 5 = 2 D. 2 + 5 = 50

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

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.
