Answer: Linear pairs of angles add up to 180 degrees. A+B=180
Step-by-step explanation: 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
Answer:
x = 4
Step-by-step explanation:
If you were to plot the given points, you would quickly see that this is a vertical line where x = 4 (a visual is always a good place to start).
Vertical lines have a slope that is undefined and are written in the form of x = .
If you had plugged into the slope formula , where (
) is (4, 8) and (
) is (4,6) the result would be as follows:
=
=
Because you can not divide by 0, the slope is in fact undefined.
