Which of the following is equation of the line through (2,3) and (-1,-12)

 y = 5x - 7

Step-by-step explanation:

(x₁ , y₁) = ( 2 , 3)    & (x₂ , y₂) = (-1 , -12)

Slope =

m = 5 & (x₁ , y₁) = ( 2 , 3)

Equation of the line:  y - y₁ = m(x -x₁)

y - 3 = 5(x - 2)

y - 3 =5x - 2*5

y - 3 = 5x - 10

    y = 5x - 10 + 3

   y = 5x - 7

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
