Answer:
the coordinates of E and G :E (-2 . -1) , G(1,0)
E G and BC are parallel has been shown in the explanation below
Step-by-step explanation:
The coordinate of E and G is
E (-2 . -1)
G(1,0)
To find out how E and G they are parallel to each other you have to find the slop between them
Slope formula is
m= y₂ -y₁ /x₂- x₁
y₁ = -1 , y₂ = 0 , x₁= -2 , x₂=1
then after putting values we get
m = 0-(-1) / 1-(-2)
m = 1/3
Now use formula to find the slope between B and C then
y₁ = 1 , y₂ = 3 , x₁= -3 , x₂=3
m = 3-1 / 3-(-3)
m = 1/3
so slope between B and C is also 1/3
