Question

find the value of k for which the line kx+ Y=6 2 X + 5 Y =1 at perpendicular to each other is​

Answer 1

Step-by-step explanation:

kX+Y =6 => Y = -kX+6 So the slope of the line compared to y=mx+c => -k

2X+5Y=1 => 5Y= -2X+1 => Y = -2/5X+1/5

So the slope of the line compared to y=mx+c => -2/5

Hence the product of slopes of lines perpendicular to each other => 2/5k = -1 =>

k = -5/2 .Hope it helps you.

Answer 2

Answer:

simple by using point of intersection yrr

2x +5y = 1

2x = 1- 5y

by hit and trail method

x =5/2
