Question

Which is an equation for the line passing through B(0,3) and C(-3,4)?
A. x-3y-9=0
B. 3x-y-3=0
C. 3x+y-3=0
D. x+3y-9=0

Answer 1

Hint: Use the two-point form

Answer 2

arrgh that should be y2-y1/x2-x1

Answer 3

That's just finding the slope right

Answer 4

yes. :) and the slope is needed in the point slope form y-y1 = m (x-x1)
you can use any of the two points to substitute in x1 and y1. ;)

Answer 5

@jhajj still there?
