Arrange the line y = (-2/5)x + 1/2 in standard form with all integer coefficients.

Standard form is either Ax + By = C or Ax + By + c = 0 depending on your text. To clear out the fractions, multiply everything by their common denominator which is 10. This will cancel out the denominators:
10y = 10(-2/5)x + 10(1/2)
10y = -4x + 5 Then move the x term (or both terms if desired) over by adding their opposite
4x + 10y = 5, or
4x + 10y - 5 = 0

standad form is ax + by = c
y = (-2/5)x + 1/2
y + 2x/5 =1/2
2x + 5y = 5/2
5/2 can remain a fraction because it is not a coefficient, it is a constant.

y = (-2/5)x + 1/2
Let's multiply both sides by 10
10y = -4x + 5
or
10y = 5 - 4x

do you mean
10y = -4x + 5 ?
or
10y + 4x -5 = 0 ?
