M∠E ≅ m∠J
m∠F ≅ m∠K
m∠G ≅ m∠L
So, m∠ L is 58.
Add 3 and 12 , cancel -2 y+2y and and add 14 and 14
3x-2y=14
12x+2y=14
15x=28
Divide both sides by 15
X=28/15
3x 28/15 -2y=14
Y=-21/5
(X,y)=28/15, -21/5
3x 28/15 -2x(-21/5)=12x 28/15 +2x(-21/5)=14
14=14=14
(x, y)=(28/15, -21/5) is the answer
I created this using a graphing calculator website called Desmos! You can use this to further explore slopes and lines and graphing in general :)
