What is the equation of the line through B and C? B = (4,2) C = (-1,-3). A.y=x+2
B.y=x−2
C.y=−2x+1
D.y=−x+2

y=x-2

Step-by-step explanation:

I graphed the equations on desmos and saw which one had those ordered pairs on the line.

4 weeks change = -20

1 week change = -5

If x is the temperature at the start of the week:

A: (4x-20)/4

B: Change per week = x-5 This means that the temperature goes down by 5 degrees per week, with x being the temperature at the start of the week.
