Consider the hyperbola $y=\frac{3}{x}$y=3x and the line $y=5$y=5.
a
To solve for the point of intersection of the hyperbola and the line, Laura forms the equation $\frac{3}{x}=5$3x=5. At how many points will the two graphs intersect?
b
Solve for the $x$x-coordinate of the point of intersection.
c
Hence state the coordinates of the point of intersection in the form $\left(x,y\right)$(x,y).
