2x+2y find the slope and y intercept

Equations can be graphed.
Expressions can't.
(2x + 2y) is not an equation.
It can't be graphed.
It has no slope, and no intercept.
It's just an expression that stands for a number.
We can't find the number until we know the values of 'x' and 'y'.

If you told us a number that's equal to (2x + 2y), THEN we'd have
an equation, which could be graphed, and it would have a slope
and an intercept.

Step-by-step explanation:

Represent the equation as follows:

Where a,b and c are decimal numbers

To solve further, we make use of trial by error method

Let

Such that

This set of digits do not follow the rule in the question

Let

The result has only 2 non zeros (4 and 8)

Hence

answers the question.

However, there are other set of numbers that can be used too
