The minimum amount of points required to make a plane is 3 points.
To find slope use the formula rise over run. Rise up from 0 to 16 then run from 0 to 2 to get rise of 16 and run of 2 (16/2). Simplify the fraction 16/2=8 (like a regular division problem) and that give you your slope. The y-intercept is 0 because the line touches the y axis (the vertical axis) at 0 :)
The answer is 19.. substitute -1 into the function whenever you see x put -1 there. This implies that 3+16 =19

Finding the extreme point :

Now,
f''( x ) at x = 1/3 and -1 is :

Therefore, it is maximum at x = -1 and minimum at x = 1/3 .
Hence, this is the required solution.
Answer:
Step-by-step explanation: one has to be 90 degrees, so 34 plus 90. The angles of a triangle always add up to 180 so, subtract the answer of 34 plus 90 from 80 and you should get the answer.
