Question

Find the slope of a line perpendicular to a line through the given points.

E(5, 7), F(3, 1)

-3
-1/3
1/3

Answer 1

find the slope of the line that connects the 2 points, then inverses it and times -1

Answer 2

find the slope of the line EF through the equation: \[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 3

So, (1-7)/(3-5)..................................................................which would be...........................-6/-2, which is the same as.........................3.

Answer 4

NEGITIVE 3 RIGHT :)?

Answer 5

With the slope of line EF, take the negative inverse of EF's slope, and make that the slope of the perpendicular line.

then take that sucker and shove him into the y =mx+b and you've got the equation of the perpendicular line.

Answer 6

^try again. negative is correct. however you also need to get the reciprocal of 3.

Answer 7

so -1/3

Answer 8

?

Answer 9

Slope is -1/3 ans.
