Equation of a line coincident with $2{\cdot}5x - 2y = 3$ is :

Question

Accepted Answer

Step 1: For coincident lines,
$$\frac{a_1}{a_2} = \frac{b_1}{b_2} = \frac{c_1}{c_2}$$
Step 2: Multiply the given equation by $2$ :
$$2(2{\cdot}5x - 2y) = 2(3) \Rightarrow 5x - 4y = 6$$
Step 3: $$5x - 4y - 6 = 0$$
Step 4: This is exactly option (D), so the two lines are coincident.

Correct option : (D)
