Question

What is the equation of the given line in standard form? Use integer coefficients.

y =5/7 x - 12
A. -5x + 7y = -12

B. -5x - 7y = -84
C. -5x + 7y = -84
D. 5x + 7y = -84

Answer 1

i recall some text not liking the first term to be negative

Answer 2

Ha ha ha..
So you are left with only one option..

Answer 3

clear the fraction and move the x to get it into

ax + by = c format

Answer 4

+7y in D is bad tho so i have to wonder

Answer 5

Standard equation can be of the type:

\[ay + bx = c\]

Answer 6

If b is negative..

Answer 7

the algebra text book we had, sullivan i believe, made us change negative x terms to be "proper" standard form.

Answer 8

In my view also x must be positive but here it depends on the choices given..

Answer 9

The Standard Form for a linear equation in two variables, x and y, is usually given as

Ax + By = C

where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

Answer 10

Yes it is very true..

Answer 11

so, none of the above :) or C is a suitable alternative that is

Answer 12

But here we must go according to the choices..

B or C ??

Answer 13

opposite signs ....

Answer 14

Yeah C we can say:

We can write that as:

\[7y - 5x = -84\]

Answer 15

Or if I could access this ID then I must edit the question and write their:

E> None of the above..

Ha ha ha..
