Question

what is the equation of the line y= -0.25x +1 in standard form? Use interger coefficients

Answer 1

standard form : Ax + By = C

y = -0.25x + 1 (add 0.25 to both sides)
0.25x + y = 1 (multiply the equation by 100 to get rid of the decimal)
25x + 100y = 100

you might better get a second opinion on this....

Answer 2

The reason I say that is because I don't know if you can solve it by turning the decimal into a fraction and solve it that way....let me show you..
.25 is the same as 1/4

y = -1/4x + 1
1/4x + y = 1 (multiply by 4 to get rid of fraction)
x + 4y = 4

I am not sure which one is correct, or if you can do it either way.

Answer 3

@Hero ...can you help with this

Answer 4

@hartnn ....are both of these answers correct ?

Answer 5

Looks good to me @texaschic101

Answer 6

so you can use either one ?

Answer 7

I think either one can be used. Whichever way you want to do it....by either multiplying by 100 or changing the decimal to a fraction

Answer 8

thanks

Answer 9

The smallest integer would likely be the correct one, so I would go with

x + 4y = 4

Answer 10

Because even if you got

25x + 100y = 100

You could still divide both sides by 25 to get

x + 4y = 4

Answer 11

Here's some alternative forms.
1.)y=-0.25(x-4)
2.)0.25x+y-1=0
Alternative form assuming x and y are real is.
3.)y=-0.25x+(1.+0.i)
