Find the midpoint of A and B where A has coordinates (2, 3)

Agata [3.3K]

Answer:

The mid-point of AB is (5,6)

Step-by-step explanation:

The mid-point of two points lies between the middle of two points or divides the line in two equal parts.

The formula for finding mid-point, M, is:

$M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point.

Given

(2, 3) and (8,9)

Putting the values in the formula

$M(x,y) =(\frac{2+8}{2} , \frac{3+9}{2})\\M = (\frac{10}{2}, \frac{12}{2})\\M = (5,6)$

Hence,

The mid-point of AB is (5,6)

-4x-2y=-12 4x+8y=-24

Alla [95]

Answer:

$x=6\\ \\y=-6$

Step-by-step explanation:

Given the system of two equations:

$\left\{\begin{array}{l}-4x-2y=-12\\ \\4x+8y=-24\end{array}\right.$

Add these two equations (left side add to left side and right side add to right side):

$-4x-2y+4x+8y=-12+(-24)\\ \\-2y+8y=-12-24\\ \\6y=-36\\ \\y=-6$

Substitute $y=-6$ into the first equation:

$-4x-2\cdot (-6)=-12\\ \\-4x+12=-12\\ \\-4x=-12-12\\ \\-4x=-24\\ \\x=6$
