Answer:

Not a solution.

Step-by-step explanation:

$-6x + 6y = - 9\\\rule{150}{0.5}\\-6(\frac{1}{2}) + 6(2) = -9\\\\-3 + 12 = -9\\\\9 =-9$

The final result is a contradiction. It is not a solution to the equation, and therefore, will not be on the line.

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre

Blizzard [7]

Answer:

A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. Vertical angles are two angles opposite from each other and those two angles are then equal.

Step-by-step explanation:

For example, if you took your typical graph with four quadrants your lines would intersect. The linear pairs are equal to 180 and the vertical angles are equal.
