Question

Which of the following is a solution of this equation?

Answer 1

Answer:

D. (-2,-3)

Step-by-step explanation:

substitute the point values of $x$ and $y$ into the equation $y=\frac{1}{2}x-2$

A. $0=\frac{1}{2}(5)-2$

   $0=2.5-2$

   $0$ ≠ $0.5$

B. $1=\frac{1}{2}(-1)-2$

   $1=-.5-2$

   $1$ ≠ $-2.5$

C. $-1=\frac{1}{2}(3)-2$

   $-1=1.5-2$

   $-1$ ≠ $-0.5$

D. $-3=\frac{1}{2}(-2)-2$

   $-3=-1-2$

   $-3=-3$
