Question

Which of the following equations is written in standard form? A. -2X=13 B. 3x+5y=-15 C.

Answer 1

B

the equation of a line in standard form is

Ax + By = C

where A is a positive integer and B, C are integers

3x + 5y = - 15 is in standard form → B

Answer 2

Equation of line in Standard form is

`ax \pm by \pm c=0,`

Among the two options given,

A. -2 x = 13

Here, coefficient of x= -2

Coefficient of y=0

But we can say that this is a point in one dimensional form.

So, it is not equation of line in standard form.

B. 3 x +5 y= -15

3 x + 5 y +15=0

Comparing with, a x + b y + c=0

a=3, b=5, c=15

Neither the coefficient of x ,nor the coefficient of y is equal to 0.

So, Option B: 3 x + 5 y = -15 →3 x+ 5 y+15=0

is equation of line in standard form.
