Answer :

To find the equation(s) of the tangent line(s) at the point(s) on the graph of the equation [tex]\(y^5 - xy - x^5 = -4\)[/tex] where [tex]\(x = 2\)[/tex], we need to follow these steps:

1. Substitute [tex]\(x = 2\)[/tex] into the given equation [tex]\(y^5 - xy - x^5 = -4\)[/tex] and solve for [tex]\(y\)[/tex]:
[tex]\[ y^5 - 2y - 2^5 = -4 \][/tex]
Simplify the equation:
[tex]\[ y^5 - 2y - 32 = -4 \][/tex]
[tex]\[ y^5 - 2y - 28 = 0 \][/tex]

Solving this equation for [tex]\(y\)[/tex] will give us the [tex]\(y\)[/tex]-coordinates of the points where the tangents occur when [tex]\(x = 2\)[/tex]. However, it turns out that this equation does not have any real solutions. This result indicates there are no real points [tex]\((2, y)\)[/tex] on the curve described by [tex]\(y^5 - xy - x^5 + 4 = 0\)[/tex].

2. Since there are no real [tex]\(y\)[/tex] values when [tex]\(x = 2\)[/tex], there are no points [tex]\((2, y)\)[/tex] on the graph where we can find a tangent line.

Therefore, we conclude that there are no tangent lines to the curve [tex]\(y^5 - xy - x^5 = -4\)[/tex] at [tex]\(x = 2\)[/tex], which means the solution to this problem is that there are no such tangent lines and therefore no equation in slope-intercept form at [tex]\(x = 2\)[/tex].
