HELP! The question says... Write an equation in point-slope form of the line through point J(4,1) with the slope -4. Can anyone HELP QUICK?
@midhun.madhu1987
Point slope form (y-y1) = m(x-x1) (x1,y1) =(4,1) m = -4 Put the values and solve
Agree @sangya21
so, the answer would be 4x+y=15?
@midhun.madhu1987 @sangya21 @KamiBug
(y -1) = -4(x-4) ------ Point slope form y -1 = -4x +16
15 or 17?
I got 15.
y -1 = -4x +16 4x + y = 17
Agreed @midhun.madhu1987 ;)
ha ha .. lol ;)
thanks you guys, will give all a medal! can yall help with another?
Sure
Most importantly.. you understood it?
Yes, I made the error when I subtracted.
fine... :)
the other question says, lines a,b,c, and d are in the same plane. line a is parallel to line c. lines b and c are perpendicular to line d. based on this, tell how lines are related. justify your answer.
Line a || Line c - given Line c perpendicular to Line d thus line d is perpendicular line a line d is perpendicular line b so how is line b related to line a?
ok.. I'm lost here. so not into geometry ://
Taking an example if line a is parallel to line b and line b is perpendicular to line c then line c is perpendicular to line a |dw:1415389227959:dw|
Got it?
yes, I get it know. so in the question I asked line a and b would be related because they are both parallel to each other?
|dw:1415389595612:dw| this is the figure of your question and the given points are Line a || Line c - given Line c perpendicular to Line d line d is perpendicular line b so how is line b related to line a? and how is line d related to line a?
|dw:1415389784071:dw|
Line a and line d are also perpendicular to each other.
correct and relation between line a and line b?
so that means, it means lines a and b are perpendicular to? *fingers crossed I got this right*
or does it mean they are parallel...
From fig do you think they are perpendicular?
b is parallel to a
ok.. thanks for your help and patience. and excuse my minor slowness. :( lol
Your welcome. :)
I'm way better in Civics and English, lol.
Civics is way above my level. Maths is easy but social is a torture.
Everyone thinks the same thing. So not true, I find it interesting unlike math sometimes.
