Question

Which equations are in standard form? Check all that apply y = 2x + 5 2x + 3y = –6 –4x + 3y = 12 y = x – 9 x + 3 = 6 x – y = 5 5x + 3y =

Answer 1

Answer:

The correct answers are:

2x + 3y = –6

and

x – y = 5

Answer 2

Answer:

The equations which are in standard form are:

$2x+3y=-6\\x-y=5$

Step-by-step explanation:

Given information

$y=2x+5\\2x+3y=-6\\-4x+3y=12\\y=x-9\\x+3=6\\x-y=5$

Now , as we know that the standard form of linear equation is:

$ax+by=c$

So,

only two equations are satisfying the standard form of liner equation among the given information.

So, the equations which are in standard form are:

$2x+3y=-6\\x-y=5$
