Step-by-step explanation:
1) , and are supplementary (given)
2) (corresponding angles theorem)
3) and are supplementary (supplements of congruent angles are congruent)

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
We have two points:
Substitute:
Substitute the value of the slope and coordinates of the second point to the equation of a line:
Finally:
No, that's not true. The input variable of a sequence is called the index, which is a counter, such as 1, 2, 3, 4, ... Note that all of these counters are positive integers. Normallly I use index i = 1 to denote the first term of a sequence, i = 2 the second term, and so on.
Decimals and irrational numbers are completely unsuitable for serving as such counters.
