Lesson 9 - Graphing Lines Review

Front

What is the definition of a slope in a graph?

Back

The slope of a line is a measure of its steepness, calculated as the change in the y-coordinate divided by the change in the x-coordinate (rise over run).

Front

How do you find the y-intercept of a linear equation?

Back

Front

What does the point (0, b) represent in a linear graph?

Back

The point (0, b) represents the y-intercept of the line, where the line crosses the y-axis.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning the line falls from left to right.

Front

What is the significance of the point (x, y) on a graph?

Back

The point (x, y) represents a specific location on the graph where x is the horizontal coordinate and y is the vertical coordinate.

Front

How can you determine the rate of change from a graph?

Back

The rate of change can be determined by calculating the slope of the line on the graph.

Front

What does the term 'linear equation' refer to?

Back

Front

What is the meaning of the term 'rise' in the context of slope?

Back

'Rise' refers to the vertical change between two points on a line, calculated as the difference in the y-coordinates.

Front

What is the meaning of the term 'run' in the context of slope?

Back

'Run' refers to the horizontal change between two points on a line, calculated as the difference in the x-coordinates.
