Question

Two equal sides of isosceles triangle are given by equation
2x - y + 1 = 0 and x + y - 3 = 0. The slope of the third side is

Answer 1

Step-by-step explanation:

Find equation BC.

 AB and AC are 

ISO sales , so AB=AC and ∠ABC=∠ACB.

slope of AB,(m1)=7 and slope of AC(m2)=−1

Let slope of BC=m

∵∠ABC=∠ACB [θ is angle between two lines]

So, slope is 

∣∣∣∣∣1+mm1m−m1∣∣∣∣∣=∣∣∣∣∣1+mm2m−m2∣∣∣∣∣

Put m1=7,m2=−1

∣∣∣∣∣1+7mm−7∣∣∣∣∣=∣∣∣∣∣1−mm+1∣∣∣∣
