**West Virginia College and Career Readiness Education Standards**. Linear relationships refer to two quantities that are related with a linear equation. Since a linear equation is a line, a linear relationship refers to two quantities on a line and their relationship to one another. This relationship can be direct or inverse. If y varies directly as x, it means if y is doubled, then x is doubled. The formula for a direct variation is y = kx, where k is the constant of variation. Read More...

Linear relationships

WV.M.8.SP. Statistics and Probability

Investigate patterns of association in bivariate data.

M.8.26. Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line and informally assess the model fit by judging the closeness of the data points to the line.

WV.M.1HS8. 8th Grade High School Mathematics I

Linear and Exponential Relationships

Represent and solve equations and inequalities graphically.

M.1HS8.11. Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality) and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.

Descriptive Statistics

Summarize, represent, and interpret data on a single count or measurement variable.

M.1HS8.41. Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line and informally assess the model fit by judging the closeness of the data points to the line.

Summarize, represent, and interpret data on two categorical and quantitative variables.

M.1HS8.45. Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.

M.1HS8.45.c. Fit a linear function for scatter plots that suggest a linear association.

WV.M.A18. High School Algebra I for 8th Grade

Linear and Exponential Relationships

Represent and solve equations and inequalities graphically.

M.A18.18. Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.

Descriptive Statistics

Summarize, represent, and interpret data on two categorical and quantitative variables.

M.A18.47. Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.

M.A18.47.c. Fit a linear function for scatter plots that suggest a linear association.
