Coordinate Plane and Slope

What does it mean if a slope is undefined?

• The line is horizontal and has a slope of zero.

• The line is vertical and does not have a slope.

• The line has a positive slope.

• The line has a negative slope.

The coordinate plane is divided by a horizontal number line called what?

• y-axis

• z-axis

• x-axis

• t-axis

How do you find the slope of a line?

• Slope (m) = (change in y) / (change in x).

• Slope (m) = (change in x) / (change in y).

• Slope (m) = y / x.

• Slope (m) = (y1 - y2) / (x1 - x2).

What does the y-axis represent in a coordinate plane?

• The horizontal number line where the y-coordinate is zero.

• The vertical number line where the x-coordinate is zero.

• The vertical number line where the y-coordinate is zero.

• The diagonal line that represents the slope of the graph.

What does it mean if a slope is zero?

• The line is horizontal and does not rise or fall.

• The line is vertical and goes straight up.

• The line has a positive slope and rises to the right.

• The line has a negative slope and falls to the right.

What is the origin in a coordinate plane?

• The point where the x-axis and y-axis intersect, represented as (0,0).

• The point where the x-axis meets the y-axis at (1,1).

• The point where the x-axis and y-axis are parallel.

• The point where the x-axis and y-axis intersect at (0,1).

What is the slope of a line that falls from left to right?

• Positive slope

• Zero slope

• Negative slope

• Undefined slope

What is an ordered pair?

• A pair of numbers (x, y) that represent a point on the coordinate plane.

• A single number that represents a point on the number line.

• A set of three numbers that define a point in three-dimensional space.

• A pair of letters that represent a point in a text document.

What are the coordinates of Point C?

• (-4, -2)

• (3, 1)

• (0, -5)

• (2, 4)

What is the slope of a line that rises from left to right?

• Negative slope

• Zero slope

• Positive slope

• Undefined slope
