Answer:
-3/6 or -1/2
Step-by-step explanation:
Step-by-step explanation:
To calculate a slope, we need to apply: 
Applying formula to each slope:

So, as you can see, there are equal pair of slopes, meaning that they are parallels, which<em> demonstrate that it's actually a quadrilateral figure.</em>
They are supplementary angles because their sum equals 180 degrees, and they are adjacent because they share a side.
If simplifying it means breaking it down with the answer it would be 1/5
Answer:
x=-2
y=5
Step-by-step explanation:
x=28-6y
2x-3y=-19
(substitute the value of x)
2(28-6y)-3y=-19
y=5
x=28-6*5
x=-2
