Unit 4 Vocab Test 2

Select the definition that most nearly defines the given word: x-intercept.

• The x coordinate of the point where the graph of a line crosses the x-axis

• When perpendicular lines have a negative reciprocal of each other

• In this method, the value of one variable from one equation is substituted in the other equation

• The y-coordinate of the point where the graph of a line crosses the y-axis

Select the definition that most nearly defines the given word: slope of parallel lines.

• When two lines intersect at right angles

• Two lines having the same y-intercept and the same slope

• Have the same slope because their rise-over-run ratio is equal

• A system of equations that has one or more solutions.

Select the definition that most nearly defines the given word: slope of perpendicular lines.

• Where you eliminate one of the variables by adding the two equations.

• When perpendicular lines have a negative reciprocal of each other

• A list of numbers x, y, z, .... that make all of the equations true simultaneously

• The x coordinate of the point where the graph of a line crosses the x-axis

Select the definition that most nearly defines the given word: system of linear equations.

• Two or more algebraic equations with the same unknown variables and the same value of the variables satisfy all such equations

• When two linear equations have the same slope (and different y-intercepts)

• A set of equations or statements that do not have a solution

• When two or more equations are working together and contain only two variables
