Answer: First Option
<em>The points have the same x-coordinate value.</em>
Step-by-step explanation:
By definition, a relation is considered a function if and only if for each input value x there exists <u><em>only one </em></u>output value y.
So, the only way that the line that connects two points in the coordinate plane is not a function, is that these two points have the same coordinate for x.
For example, suppose you have the points (2, 5) and (2, 8) and draw a line that connects these two points.
The line will be parallel to the y axis.
Note that the value of x is the same x = 2. But when x = 2 then y = 5 and y = 8.
There <u><em>are two output</em></u><em> </em>values (y = 8, y = 5) for the same input value x = 2.
In fact all the vertical lines parallel to the y-axis have infinite output values "y" for a single input value x. Therefore, they can not be defined as a function.
<u>Then the correct option is:
</u>
<em>The points have the same x-coordinate value.</em>
Answer:
3
Step-by-step explanation:
Here u can see rate of cahnge of y over x is called slope =5
So point slope form of a line
Y-y1=m(x-x1)
Y-15=5(x-3)
Answer:
30 cookies left
Step-by-step explanation:
1. Start: 48 cookies
2. Son ate ¼ of them, which is 12 (stomach ache!)
3. 36 cookies remain at this point.
4. Husband ate one-sixth of them; that's 6 cookies for him, 30 cookies left
Yes you are correct because there separated from each other
