Answer
Infinitely many solutions
Work Step by Step
$y=\frac{4}{3}x-2$
$3y-4x=-6$
$ \rightarrow 3y=4x-6$
$\rightarrow y=\frac{4}{3}x-2$
Since the lines have the same slope and y-intercept, the equations represent the same line. Any point on the line is a solution of the system, so there are infinitely many solutions.
