Answer 1

@livias.random is this right?

Answer 2

last one

Answer 3

i am just gonna check again real quick one sec

Answer 4

yep by my equation i am right what did u get @livias.random ?

Answer 5

m = (-2-2)/(-1-1)
m = -4/-2
m = 2

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

-

m = (10-1)/(-2-4)
m = 9/-6
m = -3/2

(y-1) = -3/2(x-4)
y-1 = -3/2x+6
y = -3/2x+7

-

2x = -3/2x+7
2x+3/2x = 7
7/2x = 7
x = 2

-

y = 2x
y = 2(2)
y = 4

-

(2,4)

So yep! I think you're right :)
