Answer:

y = 2x

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

If a y-intercept is below origin, then b = 0. Therefore we have the equation:

[tex]y=mx[/tex]

Put the coordinates of the point (1, 2) to the equation:

[tex]2=1m\to m=2[/tex]

Therefore:

[tex]y=2x[/tex]
