Distance of drain line from wash machine to main drain line

Hello; I am installing a new wash machine in the garage and the distance from the drain line to the other point of connection inside the house is 64 feet approx. Is the distance o.k. ? Also, I want to install 3 inch pipe with
one 45 degrees turn because of the long distance. Is that o.k. ?
Also, The slope for 64 feet is going to be 16 inches difference; do you think I can do it with a lesser slope? For example. 1 inch for every 6 feet which wil give me a total of 10 inches slope approx. ? Thank You

I believe LA is UPC code so 3" is ok for size and length.
A full size cleanout is required at the end of the run- at the washer.
You can have 1- 90 and 1- 45(135 degrees) before additional cleanouts are needed
3" needs 1/4" per ft grade to pass inspection
The washer trap is 2"
Hope this helps
