Answer:
option 2 and option 1
Step-by-step explanation:
(4)
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} } [/tex]
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 10) ← 2 points on the line
m = [tex]\frac{10-0}{2-0} [/tex] = [tex]\frac{10}{2} [/tex] = 5 , then
y = 5x
Substitute x = 16 into the equation
y = 5 × 16 = 80
