Question

Wich equation representa the line shown on the graph?

Answer 1

Answer:

the correct answer is the third one

Step-by-step explanation:

Answer 2

Answer:

y = 2x

Step-by-step 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 = $\frac{2-0}{1-0}$ = $\frac{2}{1}$ = 2

y = 2x ← equation of line
