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)

If you have 2 different slopes what is true about the slopes
Anna007 [38]

Answer:

Step-by-step explanation:

If two lines have different slopes, they cannot be the same line. If they share a y-intercept, that means they cross the y -axis at the same y value.  If they share an x value and corresponding y value, they intersect at that point, in this case their y-intercept.

Hope this helped!!
