Complete the equation of the line through (−10,−7) and (-5,-9).
Use exact numbers.

Step-by-step explanation:

(y+7)/(-9+7) = (x+10)/(-5+10)

(y+7)/(-2) = (x+10)/5

5(y+7)=-2(x+10)

5y+35= -2x-20

the equation :

5y=-2x-20-35

devided by 5

=> y = -2/5 x - 11

or y = -0.4x - 11

answer: 414,377,008

step-by-step explanation:

just multiply it

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.
