I am not sure, but I think you are talking about the least square method
Step-by-step explanation:
points (-7,5) and (5,-3)?
This would mean to subtract the y coordinates:
5 - (-3) = 8
Then subtract the x coordinates in the same order:
-7 - 5 = -12
Then divide the y result by the x result for the slope:
8/-12 is the slope.
In simplest form, this is equivalent to -2/3
Answer:
I tried looking it up, and i found 15 square units. sorry if its wrong :(
Step-by-step explanation:
Times diameter
radius is 25 cm
diameter would be 50 cm
the. You multiply 3.14 by 50 to get your answer which is 157cm
