Question

18. What is an equation for the line that passes through points (8, –3) and (9, 10)? (1 point)
(y + 3) = –13(x – 8)
(y + 3) = 13(x – 8)
(y – 3) = –13(x + 8)
(y – 3) = 13(x + 8)

Answer 1

is it.... C?

Answer 2

hang on

Answer 3

No it's the first one

Answer 4

Let me expain:

Answer 5

i mean explain:

Answer 6

so to find the slope:
10--3
over
9-8
13/1=13
m=13

Answer 7

then for point slope your formula is:
y-y1=m(x-x1)

Answer 8

So:
y--3=13(x-8)
and when you're subtracting a negative you're adding so:
y+3=13(x-8)

Answer 9

questions?

Answer 10

oh so it was minus 8 not plus...derp!

Answer 11

Yep!

Answer 12

So B is the right answer???

Answer 13
