Answer:
Study all your notes and re read everything and memorize
Step-by-step explanation:
The y intercept is where the graph crosses the y axis so it is (0,3)
The y intercept is the initial fee
Assuming you meant to write: "xy + zy"
The answer is: xy + zy = y(x + z)
The one variable that appear multiple times is: "y". There are no coefficients (other than the implied coefficients of "1"; since "1" multiplied by any number equals that very number). Since "y" appears twice, we can "factor out" a "y" ; as follows:
________________
y(x+z).

Take note of the distributive property of multiplication:
_____________________
a(b+c) = ab + ac ;
_________________
AND: a(b-c) = ab - ac.
____________________
Likewise: y(x+z) = yx +yz
= xy zy
