Answer:
Since, the given linear function is not in correct form; here's my understanding:
[tex]f(x) = - 6x + 9[/tex]
in finding the slope and y-intercept:
[tex]f(x) = mx + b[/tex]
where:
[tex]m = slope \: \: \: \: \: \: \: \: \: \: \: \: \: \\ b = y - intercept[/tex]
therefore:
[tex]m(slope) = - 6[/tex]
and
[tex]b(y - intercept) = 9[/tex]
