The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2 
EG and BD have the same slope, so they are parallel.

- 1 2 (x + 5) = -10 I need helpppppp
Anna007 [38]

Answer:

See below

Step-by-step explanation:

Do you mean -12(x+5)=-10?

Divide both sides by -12 -> x+5=10/12

Subtract 5 on both sides -> x=10/12-5 -> x=-4 1/6

So x=-4 1/6

Let me know if this wasn't the right equation
