Please help. WILL MEDAL! Use the locus definition method to write the equation of the perpendicular bisector of the line segment whose endpoints are (-2,4) and (3,5). Write the equation in general form. @ganeshie8 @TheSmartOne @sleepyjess @satellite73 @jim_thompson5910 @Directrix @mathmale @robtobey @Mehek14 @Photon336

Directrix (directrix):

The locus definition is, I think, this: All points on the perpendicular bisector of a segment are equidistant from the endpoints of that segment.

OpenStudy (okdutchman7):

Yes, I understand that part, but I'm kinda lost in the middle. I can show you what I have already done.

Directrix (directrix):

Okay

OpenStudy (okdutchman7):

I know that the perpendicular line crosses through (0.5, 4.5) because that is half way between the 2 points

OpenStudy (okdutchman7):

The slope of the line is -5

OpenStudy (okdutchman7):

I just don't know how to find where it crosses the y axis.

OpenStudy (okdutchman7):

\[y = -5x + b\]

OpenStudy (okdutchman7):

I need to find b.

Directrix (directrix):

Here is how my thinking is going. |dw:1462845306033:dw|
