Find the distance and midpoint for the points (3,4) and (19, 16).
Goryan [66]

Given parameters:

   Coordinates of the points =  (3,4) and (19, 16)

Unknown:

The distance between the points = ?

The midpoint  = ?

Solution:

  The distance between two points can be mathematically solved using;

    D  = \sqrt{(x_{2} - x_{1})^{2}  + (y_{2} - y_{1})^{2}  }

 where  x₁  = 3, x₂  = 19  and y₁  = 4, y₂  = 16

Input the parameters and solve;

   D  = \sqrt{(19 - 3)^{2} + (16 - 4)^{2}  }   = 20

Midpoint;

    The expression is given as;

     x_{m} , y_{m}  = \frac{x_{1} + x_{2}  }{2}  , \frac{y_{1} + y_{2}  }{2}

         input the parameters and solve;

                   = \frac{3 + 19}{2}  , \frac{4 + 16}{2}

                   = 11 , 10

The midpoint is (11, 10)

This table models a linear function. x −8 −4 4 8 y −3 0 6 9 plzzzzz help !!!!!!!!!!!!!!!!!!!
elixir [45]

Answer:

This is a linear function so we must first find the rise than run of the table. -8 to -4  is a run of 4  

-3 to 0 is a rise of 3


Next we divide rise/run   so 3/4  and now we know that the slope is 3/4.

This is a linear function the school or website you got this question just did not give x=0 and y=3 to mess with you the students.
