Answer:

  • y = 2x

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

  • A(1,2)

Find slope of line (m)


\\ \sf\longmapsto m=(2-0)/(1-0)


\\ \sf\longmapsto m=2

Putting in y=mx+b


\\ \sf\longmapsto y=mx+b


\\ \sf\longmapsto 2=2(1)+b


\\ \sf\longmapsto 2=2+b


\\ \sf\longmapsto b=2-2=0

Equation of the line


\\ \sf\longmapsto y=2x
