(3) Differentiating both sides of
with respect to <em>x</em> gives
Solve for d<em>y</em>/d<em>x</em> :
Then the slope of the tangent line to the curve at (1, 9) is
The equation of the tangent line would then be
<em>y</em> - 9 = -2/3 (<em>x</em> - 1) ==> <em>y</em> = -2/3 <em>x</em> + 29/3
(4) The slope of the tangent line to
at a point <em>(x, y)</em> on the curve is
When <em>x</em> = -1, we have a slope of 2/3, so
-(2<em>a</em> + 1)/(-1 - 2)² = 2/3
Solve for <em>a</em> :
-(2<em>a</em> + 1)/9 = 2/3
2<em>a</em> + 1 = -18/3 = -6
2<em>a</em> = -7
<em>a</em> = -7/2

Hi!
Step-by-step explanation:
The first thing you want to do is open up a graphing calc of your choice. For the sake of this problem, I'll be using the Desmos calc. You're gonna type in your equations into the calculator (look through attachments). You should then get two lines.
Ask yourself: Are these parallel, perpendicular, or neither.
In this case, they are parallel.
Hope this helps <3
