Question

help with explanation

Answer 1

point slope formula is:
y – y1 = m(x – x1)
first get the slope by;
y1 - y2 / x1 - x2
m = 4

now, plug in the coordinates in the right place.

x1:
9 or 10

y1:
-9 or -5

plug-in:
y + 9 = 4 (x - 9)
y + 10 = 4 (x - 10)

And that's the equation you can use either coordinates
oh and simplify it :D

Answer 2

so it would be c :)

Answer 3

how c lol :P

Answer 4

that's what i got after i simplified :p

Answer 5

Ash shouldn't it be B o_o because "y + 9 = 4 (x - 9) "

Answer 6

c is y + 9 = 4 (x + 9)

Answer 7

sure ^.^

Answer 8

one sec let go through it again annas :)

Answer 9

ooohh i get it now thanks so much!

Answer 10

no worries :D always here for help :3
