Answer is D. (–10, –30)
when x = -10 then y = <span>3x = 3(-10) = -30</span>
The answer is C - 63.2 cm
<span>The term describes a line segment that connects a vertex of a triangle to the midpoint of the opposite side is :
C. Median

Here is what you have to do first, combine like terms. On the left side do x-3x (you can do 1x-3x because x is just 1 variable, so I can see why you put 1x instead of x). Then combine -3-1. Then add the x answer on the left side to the 2x on the other side then you can figure out the rest. The reason why I want you to figure out the rest is because I'm just helping you and you need to get the answer yourself.
