4. It cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.
5. The relationship in Tuesday's table can be described by a constant unit rate.
<h3>What is a Constant Unit rate Relationship?</h3>
A constant unit rate relationship can be described as a relationship between two input and output variables, x and y, in such a way that, k = y/x. "k" is the constant of proportionality of the relationship or the unit rate between the two variables.
4. We have the following:
5/20 = 1/4
10/40 = 1/4
12/60 = 1/5
14/80 = 7/40
16/100 = 4/25
Thus, this cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.
5. 4/20 = 1/5
8/40 = 1/5
12/60 = 1/5
16/80 = 1/5
20/100 = 1/5
Thus, the value of k is the same across all table values, therefore, the relationship in Tuesday's table can be described by a constant unit rate.

Answer:
y=2x + 2
0= 2x +2
-2x = 2
x= -1
Step-by-step explanation:
2y = 4x +4
2y -4x =4
y-2x =2
-2x +y =2
2x-y=-2
