To find slope use the formula M = y2 - y1
-----------
x2 - y1
say you were given this (2,3) (-4,5) 2 would be x1 and 3 would be y1, -4 would be x2 and 5 would be y2 then just put it into the formula 5 - 3
--------
-4 - 2
which would be 2/ -6 which would simplify to 1/3
, this is best fit. But the best fit for this graph is variable b
For this case we have the following ordered pairs:
(6, 9)
(4, 6)
The scale factor can be found in two different ways:

Therefore, the scale factor is given by:
Answer:
The scale factor of the dilation is 1.5
It would be 61180 because u need to multiply 3059x20 =61180
The word decreased indicates that a negative internet should be used
