Answer:
B. y = 5x
Step-by-step explanation:
there are 2 coordinates (0,0) and (3,15)
slope m = (y2-y1)/(x2-x1)
m = (15 - 0)/(3 - 0) = 15/3 = 5
Using y = 0, x = 0, m - 5
y = mx + b
0 = 5(0) + b
b = 0
=> y = 5x

Answer: Y = 3/8
Step-by-step explanation:
You can either use the rise/run method or subtract 2 points from the line to get the slope. You can do the rise/run method by starting at a point that is on the corner of the square and keep counting how many spaces you have to go until you get to the next even point. This number will be on the bottom, then count up until you get to that even point,this amount of spaces this takes will be on top. Since there are only 2 visible points on this graph,I will use the other method. You can use either the y1-y2/x1-x2 formula or do this

Remember,the y goes on top! Our slope is 3/8,also since the y intercept is the orgin/0,0 we don't need to add it at the end. I hope this helps and wasn't too complicated!
y = 3/8(x) is the equation that represents the proportional relationship in this graph, for y in terms of x.
What is proportional?In mathematics, two sequences of numbers, frequently experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, known as the coefficient of proportionality or proportionality constant.
If corresponding elements in two sequences have a constant product—also known as the coefficient of proportionality—then the two sequences are inversely proportional.
This definition is frequently broadened to include associated varying amounts, also known as variables.
We can see that when y = 1.5, then x = 4
And when y = 3, x = 8
Putting the value in slope form
y - y1 = m(x - x1)
3 - 1.5 = m(8 - 4)
1.5 = m(4)
m = 1.5/4
m = 3/8
Now simply we put the value in y-intercept form
y - 3 = 3/8(x - 8)
y = 3/8(x) - 3 + 3
y = 3/8(x)

What is commutative property of addition?
The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.
The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.
For two numbers x and y, we have: x + y = y + x
Thus, if we take 3 numbers as a,b and c;
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
We have been given an expression;
2/7 • 53 • 7/2
53 • 2/7 • 7/2
53 • 1
53
Then all properties that were used to simplify the following problem:

Ava bought snacks for her team's practice. She bought a bag of oranges for $2.71 and a 4-pack of juice bottles. The total cost before tax was $6.75. Write and solve an equation which can be used to determine jj, how much each bottle of juice cost.
Answer: Let j be the cost of each juice bottle.
The total cost of the juice bottles is 4j. The total cost of the oranges and juice bottles is $6.75.
Thus, the equation that represents the given information is: 4j + $2.71 = $6.75. Subtract $2.71 from both sides to get: 4j = $4.04. Divide both sides by 4 to get: j = $1.01.
Therefore, each juice bottle costs $1.01.
Step-by-step explanation:
Total cost = cost of a bag of oranges + cost of 4-pack juice bottles
$6.75= $2.71 + (4 x jj)
$6.75 = $2.71 + 4jj
take similar terms: $6.75 - $2.71 = 4jj
Add similar terms: $4.04 = 4jj
Divide both sides of the equation by 4: jj = $4.04 / 4=
jj = $1.01
