Question

Ine

Determine whether KM and ST
are parallel, perpendicular, or
neither.
K(-3, -7), M(3,-3), S(0,4), T(6,-5)
a) parallel
go to station 2
b) perpendicular
go to station 10
neither
go to station 6

Answer 1

The answer is B, Perpendicular

Explanation:

KM

K= (-3, -7)

M= (3,-3)

The equation is

`(y2 - y1)/(x2 - x1)`

So (-3)-(-7) =4

And (3)-(-3)=6

-4/6= 2/3

ST

S= (0,4)

T= (6,-5)

So it would be

(-5)-(4)=-9

(6)-(0)= 6

-9/6=

-3/2

2/3 in parrallel is 2/3

2/3 in perpendicular is -3/2
