Question

Line f contains the points (5, –4) and (4, –6). What is the slope of a line perpendicular to it?

Answer 1

Can you calculate the slope of your line?

Answer 2

Line f that is

Answer 3

no how?

Answer 4

\[slope = \frac{ y _{1}-y _{0} }{ x _{1}-x _{0} }\]

Answer 5

a. 2
b. 1/2
c. -1/2
d. –2

those r the choices they give me

Answer 6

Just plug in your coords you got into that slope formula.

Answer 7

how though

Answer 8

after getting dis slope...use the formula m1*m2=-1

Answer 9

(5, –4) and (4, –6).
(x1, y1) and (x0, y0)

Got that?

Answer 10

yaaa

Answer 11

where m1 and m2 are the slopes of line and the line perpendicular to it

Answer 12

So what's the slope of f?

Answer 13

have u calculated the first slope?

Answer 14

im so confused omfg

Answer 15

ok u r given two points put it in the formula

Answer 16

(5, –4) and (4, –6).
(x1, y1) and (x0, y0)
x1 = 5, y1 = -4
x0 = 4, y0 = -6

Answer 17

(-6-(-4))/(4-5)
solve it

Answer 18

-5.5

Answer 19

-10

Answer 20

thenn

Answer 21

-6+4/-1
=-2/-1
=2

Answer 22

negative multiped by negative is positive

Answer 23

ohhhhhhhhhhhhhhh

Answer 24

right ya thanks omg ur a life savior

Answer 25

now put this m1 value in,
m1*m2=-1
u will get it
