Answer: y - e = ex - 9x +e
Explanation:
The equation of the tangent line is y -y1 = m( x - x1 )
Basically to get y1 plug in your given value(t) to your original equation
To get M to take the derivative of the original equation (e-9) and plug-in your given value(t)
and x1 is literally your given value(t)
which gives you the equation y - e = (e-9)(x-0)
now simplify to isolate y on one side
You can also plug in e as 2.72 as it is a naturally occurring number
