Question

Need help with a tangent line problem.

Answer 1

\[\Large x-2y=4 \qquad\to\qquad y=\frac{1}{2}x-2\]

`Parallel`. So what would a line look like if it's parallel to this line?

Answer 2

example:

y=2x+3
and
y=2x+4

are parallel lines

Answer 3

yeah i got up to that but would the x be -3 and 1?

Answer 4

mmm yah looks like you're on the right track.

Answer 5

\[\Large y'=\frac{2}{(x+1)^2} \qquad\to\qquad \frac{1}{2}=\frac{2}{(x+1)^2}\]You solved for x here?

Answer 6

yes :)

Answer 7

After that the points i get are (-3,2) and (1,0). Following that the equation I get after solving are y=x/2 - 1/2 and y= x/2 +5/2, but when I insert them I get them as incorrect. Any idea where I mightve made the mistake :l?

Answer 8

You must've made a silly mistake on your math somewhere :)
That other solution should be 7/2, not 5/2.
Check your addition again.

Answer 9

gotcha haha thank you so much!
