I don't quite understand Cartesian equations. I am told to

Eliminate the parameter to find a cartesian equation of the curve.

X= 3 - 4t, y= 2 - 3t there is no inequality

I don't understand what I am trying to find.

Actually, you are most familiar with Cartesian equations. That's just good old

y = f(x)

To convert parametric equations to Cartesian, eliminate the parameter t.

x = 3 - 4t

t = (3-x)/4

y = 2 - 3t

y = 2 - 3(3-x)/4

y = 2 - 9/4 + 3x/4

y = (3x-1)/4

Ta da.
