Answer:
Step-by-step explanation:
y = mx + b
The line y = 3 is a horizontal line with slope zero
y = 0x + 3
All parallel lines will also have a slope zero
a parallel line passing through (-2, 7) will have the equation
y = 0x + 7
y = 7
The graph that does not represents a proportional relationship is: A (see image attached below).
<h3>What is a Proportional Relationship?</h3>
A proportional relationship has a constant, which is uniform and is defined in the equation y = kx, as k. This means a relationship that is proportionate will have an equation in that form.
For a proportional graph, the line must pass through the point of origin which is denoted by the ordered pair, (0, 0).
Therefore, from the options given, the option B represents a proportional relationship because it contains (0, 0), while option C and D takes the form of y = kx.
Therefore, option A does not represent a proportional relationship.

Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s =
← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 =
( multiply both sides by 5 )
3 = k
s =
← equation of proportion
When t = 0.3, then
s =
= 10
5/12 /4 = 1.25/3 + 1/3 = 2.25/3
Answer:
16 groups
Step-by-step explanation:
Add all the people up then divided it by 8 so now it will be 8 people in each group and there will be a total of 16 groups
30+32+29+28+9=128/8=16
