Question

Y= -3/10 x -8 written in standard form

Answer 1

x − y = − 3

Explanation:

The standard form of a linear equation is Ax + By = C

It is most of the time also stated that A must be positive and A, B, and C should all be integers.

y = x + 3

you can subtract x from both sides, so you get:

y - x = x - x + 3

y - x = 3

This is sometimes regarded as the standard form, but most of the time, you need to make sure that A is positive, and it is currently -1. How can we change a negative number to a positive number: we multiply by -1. Also, whatever you do at the left part, you must also do at the right part:

-1 . (y - x) = -1 . 3

-y + x = -3

After some reordering you get:

x - y = -3

Answer 2

Put x and y on one side.

y = -3/10x - 8

Add 3/10x to both sides.

3/10x + y = -8

There are no fractions in Standard Form, so multiply everything by 10.

3x + 10y = -80

P.S. thanks to Piinoy for the awesome answer.
