Ok need some math assist here..

[veg1992]

This isn't even in the examples the book gives at the beginning but its in the homework part..

so I need an explanation..

Find a relationship between x and y so that (x,y) is equidistant from the two points (4,-1) and (-2, 3) in standard form.

Looking at the back the answer is 3x-2y-1 =0

I see what they did to get the slope (Midpoint formula, then changed it to it was perpendicular... but I don't get where the rest came from... that's where the help comes in and why that method is right)

what do you mean by the rest of it? that formula is standard from for a slope. Ax+By+C=0 in y=mx+b it would be y=3/2x-1/2

 

[El_Roberto]

You find the gradient using (y2-y1)/(x2-x1)=m
Then substitude the values into y-y1=m(x-x1)
then rearrange to the weird answer layout.

omg proff i didnt retain slope in school i thought it was the most pointless thing when learnign it here i am over a year later and i dont remeber a thing about it lol. meh im an artist math and english befoudns me.
