Question

Wich equation representa the line shown on the graph?

Answer 1

y = 2x

Explanation:

The equation of a line passing through the origin is of the form

y = mx ( m is the slope of the line )

To calculate m use the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

m =
`(2-0)/(1-0)` =
`(2)/(1)` = 2

y = 2x ← equation of line

Answer 2

the correct answer is the third one
