If it is a line, then pick two points on the graph   x1, y1      and  x2 , y2   

then slope = 'm' = rise/run =  (y2-y1)/(x2-x1)

If it is NOT  a line, you will need the equation of the graph and then you will take the derivative of that equation to get the slope of the graph at any given point......

There may be other ways......

Nuh-uh.    You add them !     then divide the sum by the number of terms to get the mean.  The MEDIAN will be the middle number when you list them in chrono order. (If there are TWO middle numbers from a list of terms that is even in number, then add the two middle ones and divide by two)  The mode is the number that appears most frequently....good luck!

Facts About Trapezoids

The degree measure of the four angles add up to 360 degrees. This is actually true of any quadrilateral. Let lower case letters a, b, c and d represent the angles of trapezoid ABCD.

Then: a + b + c + d = 360 degrees.

The corresponding pairs of base angles, such as A and B, or C and D, are supplementary (add up to 180 degrees).

Pasted from the internet.....50 + a = 180    a = 130      152 + ? = 180   ? = 28 degrees

(3.29 x 10^18)/(3600 x 24 x 365) = 104,325,215,627 years

y x (-y) =  -y^2

-8 -30p = -6(5p+2)

-8 -30p = -30p - 12      add 30p to both side and you will get:

-8 = -12        NOT true     ERROR !    there is no solution to this problem as written....

Agree with c-best     10/3       =   3  1/3

If it is on Earth the accelration is constant (and  irrelevant of the mass)   = 9.8 m/s^2

If he is rolling a DIE   he has 1/6th chance of getting a 5     1/6 x 270 = 45  out of 270 rolls

If he is rolling a PAIR of DICE  he has a 4 out of 36 chanc eof rolling 5    4/36 x 270 = 30 out of 270 rolls

49 (x+1)^2 = 25

(x+1)^2 = 25/49

x+1 = + - 5/7

x = 5/7 -1    or  -5/7 -1

x = -2/7 , -12/7
