When the graph of y = | 3x - 5| touches the X axis what must be true?....Y must equal zero at that point.
Set the equation you have equal to zero.
y = | 3x - 5| = 0
When will | 3x - 5| every equal zero? Only when,
3x - 5 = 0
Solve for x,
3x = 5
x = 5/3
So the graph of y = | 3x - 5| touches the axis at the point x = 5/3, y = 0,
(5/3, 0)

No. It touches the x-axis at (5/3, 0). At x=3/5, y=16/5.

no. when x=3/5, y=16/5 which is above the x-axis.
try (5/3, 0)

No, it does not. It touches the x-axis at (5/3,0).
