Answer:
8x + 20y = 5
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
y = - 0.4x + 0.25 ( multiply all terms by 20 to eliminate fractions )
20y = - 8x + 5 ( add 8x to both sides )
8x + 20y = 5 ← in standard form
