I found this works:

\override Rest #'stencil = #ly:percent-repeat-item-interface::beat-slash
\override Rest #'thickness = #'0.48
\override Rest #'slope = #'1.7

What I'm wondering now is how to define a function that lets you input a 
number and produces the slash for that number of beats.

I tried

comp = #(define-music-function (parser location x) ( integer?)
        #{
        \override Rest #'stencil = #ly:percent-repeat-item-interface::beat-slash
        \override Rest #'thickness = #'0.48
        \override Rest #'slope = #'1.7
                        
        \repeat unfold $x { r4 }
                        
        \revert Rest #'stencil
        #})

but I'm making a mistake somewhere, as I get this error message:

syntax error, unexpected NUMBER_IDENTIFIER, expecting DIGIT or UNSIGNED

pointing to the $x just after unfold.
