Question

Which equation represents the line passing through the points (3, 2) and (−9, 6)?

Answer 1

first find the slope of the line using the formula:
\[m=\frac{ y_{2}-y _{1} }{ x_{2}-x _{1} }\]

then find the equation using the equation of the line:\[y-y _{1}=m(x-x _{1})\] where (x1, y1) is any of the given points..

Answer 2

4/-12

Answer 3

so ...
y-2 = 4/-12 (x-3) ...?

Answer 4

you can simplify more 4/-12..

Answer 5

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

Answer 6

right!
then simplify: y-2 = -1/3 (x-3) in terms of y
which means, multiply -1/3 by the terms inside the bracket and transpose 2 to the right side and simplify.

Answer 7

wait im confused what do i do first?
