Equation of the line

[tex]\\ \sf\longmapsto y=2x[/tex]

Answer:

  • y = 2x

Step-by-step explanation:

The line passes through the origin and holds the point A(1, 2).

This is a proportional relationship:

  • y = kx

Considering the coordinates of the point A:

  • 2 = 1*k ⇒ k = 2

The line is:

  • y = 2x
