<h3>
Answer: y = 78</h3>
==================================
Justification #1: Angle x is 78 degrees as these two angles are corresponding angles (congruent due to the parallel lines). We also know that y = x because they are vertical angles. So by the transitive property, y = 78
Justification #2: The parallel lines mean that the alternate exterior angles are congruent, so y = 78 through one step (instead of multiple steps in the prior justification)
Answer:
The slope of the line is 
Step-by-step explanation:
Slope:
When we have two points on a line, the slope is given by the change in y divided by the change in x.
Two points on a line are M(4,5) and N(-2,9).
Change in y: 9 - 5 = 4
Change in x: -2 - 4 = -6
The slope is:

The slope of the line is 
Substitute 2 for w... in this case, you will evaluate 5(2). Just multiply and you're done.
