Answer 1

f(x) = 3x

Explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)

m =
`(3-0)/(1-0)` = 3 , then

y = 3x ← is the equation of the graphed line
