Which function represents the equation of the line?

Answer 1

y = 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 ) = (2, 6) ← 2 points on the line

m =
`(6-0)/(2-0)` =
`(6)/(2)` = 3

y = 3x ← equation of line
