Question

Write an equation of each line in standard form with integer coefficients.
4. y = 2.4x + 1.8

Answer 1

12x - 20y = -9

Explanation:

The standard form of an equation of a line:

`Ax+By=C`

We have

`4y=2.4x+1.8`

Convert

`4y=2.4x+1.8` multiply both sides by 10

`40y=24x+18` subtract 24x from both sides

`-24x+40y=18` change the signs

`24x-40y=-18` divide both sides by 2

`12x-20y=-9`
