Write y = 3/5x + 4 in standard form using integers.
a) –3x + 5y = 20
b) 5x – 3y = 20
c) –3x – 5y = 20
d) –3x + 5y = 4

 Correct option is A) –3x + 5y = 20

Step-by-step explanation:

Standard form of general linear equation is

Given equation is

Now multiply both side of equation by 5

=>

Thus correct option is A) –3x + 5y = 20

answer: c.
