-x + 2y = 10
6y = -12x + 1

6y = -12x + 1
 6           6
  y = -2x + ¹/₆

                 -x + 2y = 10
    -x + 2(-2x + ¹/₆) = 10
-x + 2(-2x) + 2(¹/₆) = 10
           -x - 4x + ¹/₃ = 10
                -5x + ¹/₃ = 10
                       - ¹/₃   - ¹/₃
                       -5x = 9²/₃
                        -5     -5
                          x = -1¹⁴/₁₅

y = -2x + ¹/₆
y = -2(-1¹⁴/₁₅) + ¹/₆
y = 3¹³/₁₅ + ¹/₆
y = 4¹/₃₀
(x, y) = (-1¹⁴/₁₅, 4¹/₃₀)

It is intersecting, making the answer equal to C.

Answer: Hence, Option 'c' is correct.

Step-by-step explanation:

Since we have given that

[tex]-x+2y=10\\\\6y=-12x+1\\\\\implies 12x+6y=1[/tex]

First we find the ratio of coefficients per variable and constant:

[tex]\dfrac{a_1}{a_2}=\dfrac{-1}{12}[/tex]

and

[tex]\dfrac{b_1}{b_2}=\dfrac{2}{6}=\dfrac{1}{3}[/tex]

and

[tex]\dfrac{c_1}{c_2}=\dfrac{10}{1}[/tex]

Since we can see that all three are not equal to each other i.e.

[tex]\dfrac{a_1}{a_2}\neq \dfrac{b_1}{b_2}\neq \dfrac{c_1}{c_2}[/tex]

so,it is considered as intersecting lines.

Hence, Option 'c' is correct.
