Algebra 1 STAAR Vocabulary Set 3

The form of a linear equations that is Ax + By = C.

• Standard form

• Point-Slope form

• Slope-Intercept form

• Literal Equation

Lines in the same plane that do not intersect. These lines have the same slope.

• Boundary line

• Perpendicular lines

• Parallel lines

• Linear Regression

Lines that intersect at 90⁰ right angles. These lines have opposite reciprocal slopes.

• Linear Regression

• Parallel lines

• Boundary line

• Perpendicular lines

Flip the fraction and take the opposite value.

• Discrete

• Opposite Reciprocal

• Solution Set

• Continuous

The set of values that make a statement true.

• Domain

• Range

• Correlation

• Solution Set

The solid or dashed line of an inequality graph. A line that divides a coordinate plane into two planes.

• Bounday Line

• Literal Equation

• Linear Regression

• Direct Variation

A linear relationship between two variables, x and y, that can be written in the form y = kx, where k is a nonzero constant. The graph of this relationship will always pass through the origin.

• Correlation Coefficient

• Correlation

• Direct Variation

• Constant of Variartion

The constant k in direct variation equations. The "k" value also represents the slope.

• Constant of Variation

• Correlation

• Correlation Coefficient

• Solution Set

A statistical method used to fit a linear model to a given data set.

• Parallel Lines

• Direct Variation

• Linear Regression

• Perpendicular Lines

A Measure of strength and direction of the relationship between two varibles or data set. A data set can have positive, negative, or no correlation.

• Correlation Coefficient

• Correlation

• Domain

• Range
