The equation of the line that goes through the points ( -9 ,-6 ) and ( -6 ,-3 ) can be written in general form A x + B y + C = 0 where B=?

Answer 1

I don't see that this can be determined with only two points. You have three unknowns.

Answer 2

Answer 3

first find the slope
slope = (-3+6)/(-6+9) = 1

So the equation must have form
x - y + C = 0
sub in either point, I pick (-6,-3)
-6 + 3 + C = 0
C = 3

so the equation is x - y + 3 = 0

looks like B = -1
