Answer:

[tex]k=26/3[/tex]

Step-by-step explanation:

we have

[tex]g(x)=3k-5x[/tex]

we know that

If the graph of g(x) passes through the point (3,11)

then

the ordered pair (3,11) must satisfy the equation g(x)

Substitute

[tex]x=3,g(3)=11[/tex]

[tex]11=3k-5(3)[/tex]

[tex]11=3k-15[/tex]

[tex]3k=11+15[/tex]

[tex]3k=26[/tex]

[tex]3k=26[/tex]

[tex]k=26/3[/tex]
