Graph the proportional relationship y=−2x by plotting points.(1 point) is it A 0,0 1,2 2,4 B 0,0 1,-2 2,-4 C 0,0 1,-1 2,-2 OR D 0,0 1,5 2,10

Answer 1

To graph the proportional relationship $y=-2x$, we can start by plotting some points based on the equation.

Let's substitute some values for $x$:

• If $x=0$: $$y=-2(0)=0\text{(Point: }(0,0)\text{)}$$

• If $x=1$: $$y=-2(1)=-2\text{(Point: }(1,-2)\text{)}$$

• If $x=2$: $$y=-2(2)=-4\text{(Point: }(2,-4)\text{)}$$

This gives us the points $(0,0)$, $(1,-2)$, and $(2,-4)$.

Now, let's check the answer choices:

A) $(0,0)$ $(1,2)$ $(2,4)$
B) $(0,0)$ $(1,-2)$ $(2,-4)$
C) $(0,0)$ $(1,-1)$ $(2,-2)$
D) $(0,0)$ $(1,5)$ $(2,10)$

Based on our calculations, the correct answer is B: $(0,0)$ $(1,-2)$ $(2,-4)$.
