Step-by-step explanation

In order to know wich equation would be appropiate, we need to compute the slope, and it should be equal to -2 because the equation is y= -2x + 3.

Additionally, the y-intercept would be at y=3 because It's expressed in the equation. The only equations that comply this condition are B) and D).

Let's compute the slope in D):

The considered ordered pairs are (x_1,y_1) = (0,3) and (x_2,y_2) = (2,2)


\text{Slope}=(y_2-y_1)/(x_2-x_1)=(2-3)/(2-0)=(-1)/(2)=-(1)/(2)

But, -1/2 is not the correct slope, in conclusion the solution is the OPTION B)
