Well, you can actually tell it is D without solving it because it is the only one that has the x value as 3.  But just to be sure.

Plug in 3 for x into the equation:
3(3)-y=9 and solve for y
9-y=9 subtract 9 from both sides
-y=0 so y=0

so the value is (3,0)

The midpoint of sm is (5,-11). One endpoint is S(3,5). What are the coordinates of endpoint M?
Nitella [24]
The coordinates of the midpoint if the endpoints are (x₁,y₁) and (x₂,y₂):
(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

One endpoint is (3,5), the midpoint is (5,-11). The other endpoint is (x,y).

\frac{3+x}{2}=5 \ \ \ \ \ \ \ \ |\times 2 \\&#10;3+x=10 \ \ \ \ \  |-3 \\&#10;x=7 \\ \\&#10;\frac{5+y}{2}=-11 \ \ \ \ \ |\times 2 \\&#10;5+y=-22 \ \ \  |-5 \\&#10;y=-27

The coordinates of endpoint M are (7,-27).
