Graphing Lines

Front

What is the y-axis on the coordinate plane?

Back

The y-axis is a vertical line (up and down) on the coordinate plane.

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form of a line is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b).

Front

How do you identify the coordinates of a point on a graph?

Back

Coordinates are identified as (x, y), where x is the horizontal position and y is the vertical position.

Front

What is the ordered pair for point A if it is located at 2 on the x-axis and 0 on the y-axis?

Back

The ordered pair for point A is (2, 0).

Front

What is the difference between a horizontal line and a vertical line?

Back

A horizontal line runs side to side (parallel to the x-axis), while a vertical line runs up and down (parallel to the y-axis).

Front

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the slope of the line represented by the equation y = 4x + 3?

Back

The slope of the line is 4.
