I dont understand what i did wrong. The awnser sheet says it is wrong but i dont understand it really. Can someone help?

#

this is what i did

#

#

i get y= 1/2x+1

#

but it is y= -1/2x

#

so you got the equation of the line passing through the points

#

but the question asks for

#

the equation of a line perpendicular to that line

#

i dont really understand it

#

my english is not the best

#

but

#

#

#

this maybe

#

but the 2nd awnser doesnt work

#

do you know what perpendicular is

#

youre just reading the questions wrong

#

orchid marsh do you know what perpendicular is

isnt it that 2 lines cross each other

#

and make a cross symbol

orchid marsh Jul 28, 2023, 12:17 PM

#

they cross and form a right angle

#

specifically a right angle

#

i dont really understand it still but

#

#

i got this

orchid marsh Jul 28, 2023, 12:35 PM

#

ok so you know how to get the slope

#

of a line

#

but you want the slope of a line perpendicular to the first line
