Answer 2

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

Answer 3

can you name two points on the line?

Answer 4

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.

Answer 5

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

Answer 6

yes

Answer 7

alternatively we can find the slope and use a point

Answer 8

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

Answer 9

ok you want me to find the slope?

Answer 10

yes

Answer 11

-1/2

Answer 12

u there?

Answer 13

yes

Answer 14

thats correct

Answer 15

now you can use point slope form
using the point (1,-3)

y - (-3) = -1/2 ( x - 1 )
