Coordinate Graphing

What are the four quadrants in a coordinate graph?

• Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y)

• Quadrant I (negative x, positive y), Quadrant II (negative x, negative y), Quadrant III (positive x, negative y), Quadrant IV (positive x, positive y)

• Quadrant I (positive x, negative y), Quadrant II (positive x, positive y), Quadrant III (negative x, positive y), Quadrant IV (negative x, negative y)

• Quadrant I (positive y, positive x), Quadrant II (positive y, negative x), Quadrant III (negative y, negative x), Quadrant IV (negative y, positive x)

What is a coordinate graph?

• A three-dimensional space used for plotting shapes.

• A two-dimensional plane formed by the intersection of a horizontal axis (x-axis) and a vertical axis (y-axis), used to plot points, lines, and curves.

• A type of graph that only displays linear equations.

• A method for calculating distances between points on a map.

How do you plot a point given an ordered pair?

• Start at the origin, move x units along the x-axis, and then move y units up (if positive) or down (if negative) to locate the point.

• Move y units along the y-axis first, then x units along the x-axis to find the point.

• Plot the point at (x, y) without any movement from the origin.

• Draw a line from the origin to the point without measuring x and y units.

How do you identify the y-value in an ordered pair?

• The y-value is the first number listed, indicating the horizontal position on the graph.

• The y-value is the second number listed, indicating the vertical position on the graph.

• The y-value is the average of the two numbers in the ordered pair.

• The y-value is the sum of the two numbers in the ordered pair.

What does it mean for points to be collinear?

• Points are collinear if they lie on the same straight line.

• Points are collinear if they form a triangle.

• Points are collinear if they are equidistant from each other.

• Points are collinear if they lie on different planes.

What does an ordered pair represent in coordinate graphing?

• A specific point on a coordinate graph, where the first number is the x-coordinate and the second number is the y-coordinate.

• A line segment connecting two points on the graph.

• The distance between two points on the graph.

• A set of equations that define a graph.

What is the significance of the origin in a coordinate graph?

• It is the point where the x-axis and y-axis intersect, serving as the reference point for all other points.

• It represents the maximum value on the graph.

• It is the point where all values are negative.

• It indicates the direction of the graph's slope.

What is the distance formula used for in coordinate graphing?

• To calculate the area of a triangle in a coordinate plane.

• To determine the slope of a line between two points.

• To calculate the distance between two points in a coordinate plane, given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

• To find the midpoint of a line segment between two points.

How do you identify the x-intercept and y-intercept of a line?

• The x-intercept is where the line crosses the y-axis, and the y-intercept is where it crosses the x-axis.

• The x-intercept is the point where the line crosses the x-axis (y=0), and the y-intercept is the point where the line crosses the y-axis (x=0).

• The x-intercept is the slope of the line, and the y-intercept is the angle of the line.

• The x-intercept is the point where the line is horizontal, and the y-intercept is the point where the line is vertical.

How can you determine if three points are collinear?

• By checking if the distance between any two points is equal

• By calculating the area of the triangle formed by them and checking if it is zero

• By ensuring that the points are all on the same horizontal line

• By measuring the angles between the lines connecting the points
