How can you identify a linear equation from a table of values?

Back

You can identify a linear equation from a table of values by checking if the differences between consecutive outputs (y-values) are constant.

What does a positive slope indicate in a linear graph?

Back

A positive slope indicates that as the x-values increase, the y-values also increase.

What does a negative slope indicate in a linear graph?

Back

A negative slope indicates that as the x-values increase, the y-values decrease.

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

How do you determine the slope from a graph?

Back

The slope can be determined by selecting two points on the line and using the formula (change in y) / (change in x).

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.

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

Back

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

What does the term 'rate of change' refer to in linear functions?

Back

The rate of change refers to how much the output (y) changes for a unit change in the input (x), which is represented by the slope.

How can you represent a linear equation in slope-intercept form?

Back

A linear equation can be represented in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept.
