Answer:
(0, 7)
Step-by-step explanation:
The point that crosses the y-axis is called the y-intercept of the line.
We are given an equation of the line and we need to determine the y-intercept. This can be done by determining the constant in the equation.
What are constants?
Constants are such terms that include only numbers. There should be no variables in constants.
<u>We know that:</u>

The constant we can see in the equation is "7". Therefore, the y-intercept is 7.
Note: The y-intercept of the line must have an x-coordinate of 0.
<u>Therefore,</u>
⇒ Coordinates of y-intercept: (x, y) ==> (0, 7).
Answer:

Step-by-step explanation:
Given: See the attached image
To find: the function represented by the table
Solution:
A function is a relation in which every element of the domain has a unique image in the co-domain.

Here,
are elements in the domain and
are elements in the co-domain.
Therefore, the table represents the function 
You can use a factor tree, and if you dont know how to use one, look it up on youtube, theres tons
