Question

Find the equation of a straight line passing through the points A (-6, 2) and B (1, -5)?

Answer 1

Answer:

Equation of any line is y=mx+c

here m is slope of line  

so we have m=−3

y=−3x+c

Also this line passes through (6,2)

2=−18+c⇒c=20

so equation of line will be y+3x=20

or 3x+y−20=0.
