Write the equation in standard form using integers.

Question

y+1=4/5(x=4)

Answer 1

if by "y+1 = (4/5)x=4

you meant

y+1 = (4/5)(x-4)

then

multiply by 5 to eliminate the fraction,

and collect like terms the constant terms

5y+5 =4x-16

put x and y terms on the same side, constant term alone on the other side

4x-5y =5+16

4x-5y = 21 is in standard form: ax+by= c where a=4, b=5, c=21

but if you meant, with +4 instead of -4

y+1 = (4/5)(x+4)

then

5y+5 = 4x+16

4x-5y= 5-16

4x-5y = -11 in standard form

the +, - and = keys often get confused if your fingers hit the wrong key

Answer 2

5(y + 1) = 4(x + 4)

5y + 5 = 4x + 16

4x - 5y = 11
