x + 3y -15 = 0

Step-by-step explanation:

let (x,y) be the coordinate of bisector,

so (x,y) should be equal distance from point (8,9) and (4,-3)

(x-8)^2 + (y-9)^2 = (x-4)^2 + (y-(-3))^2

or, (x^2 - 16x + 64) + (y^2 - 18y + 81 )= (x^2 -8x + 16) + (y^2 + 6y + 9)

After cancelling x^2 and y^2 from both side, we get

-16x - 18y +145 = -8x +6y + 25

or, -16x + 8x - 18y - 6y +145 -25 = 0

or, -8x - 24y + 120 = 0

or -8 ( x + 3y - 15) = 0

or, x + 3y - 15 = 0 ------ this is the equation of the perpendicular bisector of line segment with endpoints (8,9) and (4,-3)

A line with a slope of -4 has a coordinate of (0,3). If the other coordinate is (6,t),
s2008m [1.1K]

Answer:

Alrighty! So this is what we know:

Slope (m) = (-4)

Co-ordinate (0,3)

Co-ordinate 2 (6,t)

t = ?

Let's find our equation...

y=mx+b <-- just plug what we know in...

3=(-4)0+b

3=0+b

b=3

We just found b! woohoo

Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).

SO-

t=y

plug it in our equation...

y=mx+b

t=(-4)x+3

t=(-4)(6)+3

t=(-24)+3

t=(-21)

SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)
