The formula of a slope:

We have the points (-4, -3) and (-3, s) and the slope m = 3. Substitute:
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6.
Step-by-step explanation
Find the diagram attached
First you must note that the sum of two supplementary angles is 180°
Also, since the sum of angle on a straight line is 180°, the angles that are supplementary must lie on the same straight line.
Based on the diagram, the pair of angles that lies on the same straight line are ∠4 and ∠3, ∠4 and ∠5 and ∠3 and ∠6. If that is the case, hence this angles are supplementary.
Factor the numerator and factor the denominator.

Then you divide the numerator and the denominator by the common factor to reduce the fraction.
Answer:
an = 4^(n-1)
Step-by-step explanation:
The three given terms have a common ratio of 4:
4/1 = 16/4 = 4
So, this can be described by the function for a geometric sequence:
an = a1×r^(n -1)
where an is the n-th term, a1 is the first term (1) and r is the common ratio (4).
an = 1×4^(n-1)
an = 4^(n -1) . . . . . simplified
Answer:
2 units^2
Step-by-step explanation:
The area of a triangle is given by the formula
A = 1/2 bh where b is the length of the base and h is the height
b = 2 and h =2
A = 1/2 (2) * (2)
A = 1/2*4
A = 2 units^2
