Question

What is y=-3/10x-8 written in standard form

Answer 1

Standard form is ax + by = c

so the answer is

-3/10x - y = 8

Answer 2

Put x and y on one side.

y = -3/10x - 8
Add 3/10x to both sides.
3/10x + y = -8
Because there are no fractions in Standard Form, multiply everything by 10.
3x + 10y = -80
