What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm'. It is calculated as the change in y divided by the change in x (rise over run).

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is a solution to an inequality?

Back

A solution to an inequality is a value that makes the inequality true when substituted into it.

Front

Back

It means that when you substitute the number for x, the resulting statement must be true.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

Back

In the equation, 'm' represents the slope and 'b' represents the y-intercept.

Front

What is the formula for the slope-intercept form of a line?

Back

The slope-intercept form is given by the equation: y = mx + b, where m is the slope and b is the y-intercept.

Front

Back

To solve, add 15 to both sides: 18 \\leq 3x, then divide by 3: 6 \\leq x, or x \geq 6.

Front

What is the significance of a negative slope?

Back

A negative slope indicates that as x increases, y decreases, showing a downward trend in the graph.

Front

What does it mean if a line has a slope of zero?

Back

A slope of zero means the line is horizontal, indicating that y remains constant regardless of x.
