b. (4, 5)
c. (6, 4)
d. (4, 6)

2 true or false
point a and point b have the same y - coordinate.

3 wyatt asked his friends how many hoodies they had. what kind of data was he collecting?
a. categorical data that changes over time
b. numerical data that changes over time
c. categorical data that does not change over time
d. numerical data that does not change over time

Explanation:

Question 1

Step1: Recall coordinate system rules

In a coordinate system, a point \((x,y)\) has \(x\) as the horizontal (left - right) value and \(y\) as the vertical (up - down) value. To find the coordinates of point \(D\), we count the number of units to the right (for \(x\)) and up (for \(y\)) from the origin \((0,0)\).

Step2: Determine \(x\) and \(y\) for point \(D\)

Looking at the graph (even though it's partially visible, from the options and the general grid - based coordinate system), if we assume the grid is such that for point \(D\), the horizontal (x - axis) count is 6 and the vertical (y - axis) count is 4. So the coordinates of point \(D\) are \((6,4)\).

Step1: Recall y - coordinate definition

The \(y\) - coordinate of a point in a coordinate system is the vertical distance from the \(x\) - axis. Let's assume Point \(A\) and Point \(B\) are on the given grid. From the grid, we can see that Point \(A\) and Point \(B\) have different vertical positions (different \(y\) - coordinates). For example, if we look at the \(y\) - axis values, one point might be at a different \(y\) - level than the other. So the statement "Point \(A\) and Point \(B\) have the same \(y\) - coordinate" is False.

Step1: Define data types

• Categorical data is non - numerical (like colors, types of animals), while numerical data is data that is in the form of numbers (like counts, measurements).
• Data that changes over time is time - series data, and data that does not change over time is cross - sectional data.

Wyatt is asking for the number of hoodies, which is a numerical value (count). Also, the number of hoodies a person has at a given time is not related to time - based change (he is just collecting the current number of hoodies, not how it changes over time). So it is numerical data that does not change over time.

Answer:

c. \((6,4)\)
