Write an equation of each line in standard form with integer coefficients.<br> 4. y = 2.4x + 1.8
Nadusha1986 [10]

Answer:

<h2>12x - 20y = -9</h2>

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          <em>multiply both sides by 10</em>

40y=24x+18          <em>subtract 24x from both sides</em>

-24x+40y=18            <em>change the signs</em>

24x-40y=-18          <em>divide both sides by 2</em>

12x-20y=-9

Does it help to remember and/or list out your square roots
ololo11 [35]
It is a good thing to remember. Of course, not all, but some basic numbers that appear all the time such as the numbers from 2 to 13 should be remembered as they appear in numerous assignments and tests.
