Understanding Scatter Plots and Coordinate Systems Quiz

An ordered pair is used to represent the location of a point on a coordinate plane by specifying its x and y coordinates.

In a Cartesian coordinate system, the horizontal axis is called the x-axis. The vertical axis is called the y-axis, while the z-axis is used in three-dimensional space. There is no standard named t-axis in Cartesian coordinates.

In a Cartesian coordinate system, the vertical axis is commonly referred to as the y-axis.

A scatter plot is used to represent two-variable data by using dots, not bars (bar graph), lines (line chart), or sections of a circle (pie chart).

In a coordinate plane, Quadrant 1 is where both the x and y variables are positive. This is the top-right section of the plane.

In the coordinate plane, Quadrant 4 is where the x-values are positive and the y-values are negative. This is the bottom right quadrant when looking at the plane.

A line of best fit is used to represent the general trend in a scatter plot by minimizing the distance of data points to the line.

In a coordinate plane, Quadrant 3 is the area where both the x and y variables of ordered pairs are negative. Quadrant 1 has positive x and y values, Quadrant 2 has negative x and positive y values, and Quadrant 4 has positive x and negative y values.

In a scatter plot, the pattern that the data follows is called the trend. It represents the general direction in which the data points are moving. Clusters refer to groups of data points that are close together, outliers are data points that are significantly different from the rest, and the line of best fit is a line that represents the overall trend in the data.

In a coordinate plane, Quadrant 2 is where the x-variable is negative and the y-variable is positive. Quadrants 1, 3, and 4 have different combinations of positive and negative variables.

In mathematics, the rate of change in a linear equation is known as the slope. It represents how steep or gradual the line is. The terms Gradient, Intercept, and Incline are not used to describe the rate of change in linear equations.

The Y-intercept is the point where the line crosses the y-axis when x = 0 in a linear equation. This point represents the initial value of the function.
