Question

anonymous · Answer

anonymous · Answer

y – 3 = –½(x + 1)
       y = ½x + 5
       y – 3 = ½(x + 1)
       y + 3 = –½(x – 1)

perl · Answer

can you name two points on the line?

perl · Answer

We can derive the equation of a line if we can find two points on the given line, or if we can find the slope and a point of the given line.

perl · Answer

I see an x intercept of -5, which is the point (-5, 0) 
and I see the point ( 1, -3 )

anonymous · Answer

yes

perl · Answer

alternatively we can find the slope and use a point

perl · Answer

ok so lets find the slope, since we know two points on the line

anonymous · Answer

ok you want me to find the slope?

perl · Answer

yes

anonymous · Answer

-1/2

anonymous · Answer

u there?

perl · Answer

yes

perl · Answer

thats correct

perl · Answer

now you can use point slope form 
using the point (1,-3)

y - (-3) = -1/2 ( x - 1 )
