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

Nadusha1986 [10]

Answer:

Step-by-step 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

$12x-20y=-9$
