Determine the equation of the perpendicular bisector JK whose endpoints are J(-4,9) and K(6,1). Show all your work below. (Use of the grid is optional.)

Step-by-step explanation:

Coordinates of segment with endpoints J and K are,

J(-4, 9) and K(6, 1)

Midpoint of the segment JK =

                                               =

                                               = (1, 5)

Slope of JK,

                             =

                             =

Let the equation of perpendicular bisector passing through and slope is,

By the property of perpendicular lines,

Therefore, equation of the line passing through midpoint (1, 5) and slope = will be,

sorry if this isnt what you're looking for i dont really understand the question

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
