Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 10) ← 2 points on the line

m = $\frac{10-0}{2-0}$ = $\frac{10}{2}$ = 5 , then

y = 5x

Substitute x = 16 into the equation

y = 5 × 16 = 80
