What do you need help on with this function?

also f(x)= 5x-8 find all x intercepts and y intercepts
and what is the answer step by step please? thank you.

f(x) = 5x - 8

this is in slope-intercept form (y = mx+b) where y = f(x)
solve for x and y like you have been taught. Please provide us with detail on where you are stuck.

Cheers,
John.

i guess on the first equation it said this" for the f(x)=-3x+7 find the value of x that leads to the given value of f(x).

thanks john for helping.
