Front

What is the slope of a line?

Back

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

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 the value of y when x = 0.

Front

How do you find the slope from an equation in slope-intercept form?

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

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

Back

Front

Back

The slope is -2.

Front

Back

The y-intercept is 3.

Front

How do you write the equation of a line given a slope and y-intercept?

Back

Front

What is the meaning of the y-intercept in a real-world context?

Back

The y-intercept represents the starting value of a situation when the independent variable (x) is zero.
