Front

What is the effect of changing the slope of a linear function?

Back

Changes the steepness of the line.

Front

How does the y-intercept affect the graph of a linear function?

Back

Determines where the line crosses the y-axis.

Front

How does adding a constant (b) to the equation of a proportional relationship y = mx affect the line on a graph?

Back

Translates the line.

Front

What does the slope of a linear function represent?

Back

Rate of change.

Front

If a linear function has a slope of 2 and a y-intercept of -3, what is the equation of the function?

Back

y = 2x - 3.

Front

What is the definition of slope in a linear function?

Back

The ratio of the change in y to the change in x, representing the steepness of the line.

Front

What does a positive slope indicate about a linear function?

Back

The function is increasing as x increases.

Front

What does a negative slope indicate about a linear function?

Back

The function is decreasing as x increases.

Front

What is the y-intercept of a linear function?

Back

The point where the line crosses the y-axis.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).
