Question
0.3 - 0.4y =7.5  in standard form

Answer
The key question is - what is the "standard" form?
This must be something introduced previously in your textbook or in your class.

I guess you need to rewrite the equation in the form y=m*x+b, where m is the slope of the line, b is the point where the line intersects the y-axis.

If this is what you want, then, you have to add or subtract some number on both sides of the equation, so that you isolate the "y" term on one side of the equation. The second step is to multiply or divide both sides by some number, if necessary, so that instead of 0.4y, you have "y" on one side of the equation.

There must be a typo in your question, since "x" is no where to be seen. Assuming that it reads "0.3-0.4y=7.5x", then

step 1: subtract 0.3 from both sides of the equation
=> -0.4y=7.5x-0.3
step 2: divide both sides by -0.4
=> y= -(7.5/0.4)x + (0.3/0.4)
