Question

what can you say about the lines drawn on the graph for the following system of linear equations x + 2y + 4 = 0 and 3x + 6y + 12 = 0

Answer 1

Answer:

Step-by-step explanation:

First eq. is x + 2y + 4 = 0

Second eq. is 3x + 6y + 12 = 0;

Multiplying 3 in both side of eq. 1;

we get

3x + 6y + 12 = 0;

Which equal to the eq. 2;

Both are the linear equation are similar:

No difference between the equation, Here x + 2y +4 = 0 is the simplest form of  eq. 3x + 6y + 12 = 0;

Answer 2

Answer:

both equations are of same line

Step-by-step explanation:

x + 2y + 4 = 0

2y = -x -4

y = -x/2  - 2

slope of line = -1/2

3x + 6y + 12 = 0

=> 6y = -3x - 12

=> y = -x/2 - 2

slope of line = -1/2

both equations are of same line
