Answer:
12x - 20y = -9
Step-by-step explanation:
The standard form of an equation of a line:
[tex]Ax+By=C[/tex]
We have
[tex]4y=2.4x+1.8[/tex]
Convert
[tex]4y=2.4x+1.8[/tex] multiply both sides by 10
[tex]40y=24x+18[/tex] subtract 24x from both sides
[tex]-24x+40y=18[/tex] change the signs
[tex]24x-40y=-18[/tex] divide both sides by 2
[tex]12x-20y=-9[/tex]
