Please help.

Answer 1

Answer:

B

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 ) = (4, - 2) ← 2 points on the line

m = $\frac{-2-0}{4-0}$ = $\frac{-2}{4}$ = - $\frac{1}{2}$ , then

y = - $\frac{1}{2}$ x → B

Answer 2

y = - 1/2x
