A line segment has endpoints at (2,10) and (10,2). What are the coordinates of the midpoint of the line segment?

IrinaVladis [17]

Answer:

(6,6)

Step-by-step explanation:

The midpoint formula is $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$ . Substitute (2,10) and (10,2) into this formula and simplify.

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ) \\(\frac{2+10}{2},\frac{10+2}{2} ) \\(\frac{12}{2},\frac{12}{2} ) \\(6,6)$

The value of x is 5/6 and y is 8/5.

Step-by-step explanation:

Given,

12x+15y=34 Eqn 1

-6x+5y=3 Eqn 2

Multiplying Eqn 2 by 2

$2(-6x+5y=3)\\-12x+10y=6\ \ \ Eqn 3$

Adding Eqn 1 and 3

$(12x+15y)+(-12x+10y)=34+6\\12x+15y-12x+10y=40\\25y=40$

Dividing both sides by 25

$\frac{25y}{25}=\frac{40}{25}\\y=\frac{8}{5}$

Putting y= 8/5 in Eqn 1

$12x+15(\frac{8}{5})=34\\12x+3*8=34\\12x+24=34\\12x=34-24\\12x=10$

Dividing both sides by 12

$\frac{12x}{12}=\frac{10}{12}\\x=\frac{5}{6}$

The value of x is 5/6 and y is 8/5.
