Carlos and Ethan noticed that both proportional relationships and linear functions form a straight line when graphed. Carlos claims that all linear functions are also proportional relationships. Ethan disagreed and tells Carlos that he has it backwards, that all proportional relationships are linear functions. Which statement accurately compares their observations?
A) Carlos is correct because all linear functions go through the origin.
B) Ethan is correct because all proportional relationships form a straight line and go through the origin and linear functions are linear, but they don’t all go through the origin so they are not always proportional.
C) Carlos is incorrect because no proportional relationships are linear.
D) Both Carlos and Ethan are incorrect, no proportional relationships are nonlinear.
Answers
Answer:
B. Ethan is correct because all proportional relationships form a straight line and go through the origin and linear functions are linear, but they don’t all go through the origin so they are not always proportional.
Step-by-step explanation:
So a proportional relationship is just a special kind of linear relationship, i.e., all proportional relationships are linear relationships (although not all linear relationships are proportional).

Answers
Answer:
The independent variable on the x-axis is the price of a t-shirt and the dependent variable on the y-axis is the number of t-shirts sold.
Step-by-step explanation:
To understand this question, it is crucial to understand what independent and dependent variables are. The independent variable is the one that is manipulated in an experiment. On the other hand, the dependent variable is the one that changes because of a change in the independent variable.
In this problem, the independent variable is the price of a t-shirt. Sera is able to change the price of her t-shirts at will, and changing it will impact the number of t-shirts sold. So, the dependent variable is the number of shirts sold. Sera has no direct control over this variable. She hopes that she will be able to control it by changing the cost of the t-shirts she sells.
Therefore, the independent variable is the price of a t-shirt and the dependent variable is the number of t-shirts sold.

What is 4x-2y=8 in slope intercept form?
Answers
Answer: y = -2x + 4
Step-by-step explanation: In slope-intercept form or y = mx + b form,
the y is isolated or by itself on the left side of the equation.
So start by subtracting 4x from both sides.
That gives us -2y = 4x - 8.
Notice I put the x term first because in y = mx + b form,
the x term comes first on the left side of the equation.
From here, we divide both sides by -2 to get y = -2x + 4.
Y=2x-4
m=2, b= -4
