Answer:
I attached pictures of the two graphs, I hope they help!
Step-by-step explanation:
6)
34, 43, 52, 61, ...
43-34 = 9; 52-43 = 9; 61-52 = 9
The difference between one term and the next is a constant so it is arithmetic sequence
first term: a = 34
difference: d = 9
so the formula:

7)
10, 6, 2, -2, ...
6-10 = -4; 2-6 = -4; -2-2 = -4
The difference between one term and the next is a constant so it is arithmetic sequence
first term: a = 10
difference: d = -4
so the formula:

8)
-3, -10, -17, -24, ...
-10-(-3) = -7; -17-(-10) = -7; -24-(-17) = -7
The difference between one term and the next is a constant so it is arithmetic sequence
first term: a = -3
difference: d = -7
so the formula:

9)
7, 8.5, 10, 11.5, ...
8.5-7 = 1.5; 10-8.5 = 1.5; 11.5-10 = 1.5
The difference between one term and the next is a constant so it is arithmetic sequence
first term: a = 7
difference: d = 1.5
so the formula:

10)
30, 22¹/₂, 15, 7¹/₂, ...
22¹/₂-30 = -7¹/₂; 15-22¹/₂ = -7¹/₂; 7¹/₂-15 = -7¹/₂
The difference between one term and the next is a constant so it is arithmetic sequence
first term: a = 30
difference: d = -7¹/₂
so the formula:

Hey there! Hello!
Not sure if you still need these answers, but I'd love to help out if you do!
Now, I want you to go ahead and think of some stuff that's true for squares. To name a few, the opposite sides are going to be parallel to one another, all the angles are 90°, all the sides are the same length, and both diagonals are going to be perpendicular and equal in length. I'm sure there's even more, but I'll leave that to you. (BTW, by diagonals, I mean the lines that go through the the opposite diagonal corners).
What about rectangles? The opposite sides are going to be parallel to one another, the diagonals are going to be equal in length, and the angles are going to be 90°.
Now, rhombi. All sides are going to be equal, opposite sides are going to be parallel, the diagonally opposite angles will be equal to each other, and the diagonals bisect each other at 90°.
And lastly, parallelograms. Pretty similar to rhombi in that they have parallel opposite sides and that the opposite diagonal angles are equal to each other, but there's one thing that makes a parallelogram not a rhombus.
If you differentiate the stuff I described, you'll be golden. There's a lot to choose from, and I personally like to have options. Hope this helped you out, feel free to ask me any additional questions you have! :-)
ANSWER
First proved that line p is parallel to line r
to proof
As given in the question
∠1 ≈∠5
∠1 and ∠5 are corresponding angles
by using the property of the corresponding angles
two lines are cut by a transversal so that the corresponding angles are
congruent, then these lines are parallel.
As shown in diagram q is transversal line.
Thus by using the above property
line p is parallel to line r.
proof of 1(a)
REASON
Vertically opposite angle
The pair of angles formed when two lines intersect each other are called vertically opposite angles.
Thus
∠4 and ∠1 are vertically opposite angle
thus
∠4 ≈∠ 1
proof of 2(b)
REASON
Alternate interior angle
the pairs of angles on either side of the transversal and inside the two lines are called the alternate interior angles . If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent .
as line p is parallel to line r (proof above)
q is transversal
thus
∠4 ≈∠ 5
Hence proved
proof of 3 (c)
As ∠4 ≈∠5 (proof above)
REASON
If two lines are cut by a transversal so that the alternate interior angles
are congruent, then these lines are parallel.
Thus by above property
line p is parallel to line r
Hence proved
