Explanation / Answer

-3,0 and -5,14.8

a)
slope = (14.8 - 0) / (-5- (-3))
= 14.8/-2
= -7.4

----------------------------------------------------------------

b)
From -5 to -4,
y changes by the slope

So, y changes by
-7.4

---------------------------------------------------------------

c)
We were at 14.8 at x = -5
So, at x = -4, we get 14.8 + (-7.4)
7.4 ---> ANS

---------------------------------------------------------------

d)
Yes, it is
