Write `y = -0.4x + 0.9` in standard form using integers.

Answer 1

To write the equation y = -0.4x + 0.9 in standard form using integers, we need to eliminate the decimal.

First, let's multiply the entire equation by 10 to get rid of the decimal:

10y = -4x + 9

Next, let's move the -4x term to the left side by adding 4x to both sides:

4x + 10y = 9

So, the equation y = -0.4x + 0.9 in standard form using integers is 4x + 10y = 9.
