Use the following ordered pairs
Lynna [10]

The ordered pair for Y is (-4,-2)

Step-by-step explanation:

Given

X(-2,3)

Z(-6,-7)

As Y is the mid-point of XZ, it will divide Xz in two equal segments. Y is the mid-point of the segment.

Let (x_Y, y_Y) be the coordinates of the mid-point

Then

(x_Y, y_Y) = (\frac{x_1+_2}{2} , \frac{y_1+y_2}{2})

Putting the values

=(frac{-2-6}{2} , \frac{3-7}{2})\\=(\frac{-8}{2} , \frac{-4}{2})\\=(-4, -2)

Hence,

The ordered pair for Y is (-4,-2)

Given a = 4 and b = -2, evaluate -|b - a|. Please help!
Sergeeva-Olga [200]
The answer is:  - 6 .
_____________________________________________

Evaluate the value INSIDE the "bars". 
  b - a  =  -2  -  4  = -6 .  The absolute value of the value inside inside the bars is the "positive" number of that value.  The value is negative 6; so, the absolute value, or "magnitude", of "-6", is "6";  Then, then "-" (6) = -6.  So the answer is: -6 .
