Answer:
A
Step-by-step explanation:
When a slope is undefined, it is always x = ?
The point (-5, -8) tells us that x = -5
Option A also has a point with x = -5
Answer:

Step-by-step explanation:
To find
, we need to eliminate
in this system of equations:
(1)
(2)
From (1) and (2):


Then, we equalize both expressions and solve for
:




<h3>
Answer: Yes, it is a function</h3>
This is a function because there are no x values that repeat.
If we had repeated x values, then this would mean a certain input x leads to multiple outputs y, and that would not make it a function.
For instance, if we had (2,1) and (2,2) at the same time, then the input x = 2 leads to multiple outputs y = 1 and y = 2 at the same time. A function would not be possible in this example.
A function is only possible if any input x leads to exactly one output y. It is possible for y to repeat itself and still have a function.
x = 85 degrees and
y = 45 degrees.
Step-by-step explanation:
Step 1:
The angle for a straight line is 180°. The sum of the angles in a triangle is 180°. These two statements are required to solve this problem.
The angles of x° and 95° are on a single straight line.
So 

So the angle of x is 85°.
Step 2:
The sum of the angles in a triangle is 180°.
So 


So the angle of y is 45°.
