Question

Find the equation of the line passing through the point of intersection 2x-y+5=0,x+y+1=0 and origin

Answer 1

Answer:

3x−y+5=0

2x+y−15=0

Solving these two equations simultaneously

x=2

y=11

Point 1=(2,11)

Point 2=(0,0) (origin)

Equation of line passing through 1&2

y=mx+c

Here passes through (0,0)

0=0+c

c=0

y=mx

11=m×2
