-12 degrees.
Each hour, the temperature dropped by 3 degrees so it'd look like:
-3
-6
-9
-12
Point-slope form: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)
Data:
(1,1)
m=2
Therefore:
y-y₀=m(x-x₀)
y-1=2(x-1) This is the equation of the line in point-slope form.
Answer. y-1=2(x-1)
I got the second one as my answer.....
8/a^5 x a
2.9 because 1.16 plus 1.16 is 2.32. If each is a pound split it in half and add 2.32 it and y'all get 2.9
