What does the slope represent in a graph?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

What does the y-intercept represent in a graph?

Back

The y-intercept represents the value of y when x = 0, indicating the starting point of the graph.

How do you identify the slope from a linear equation in slope-intercept form?

Back

The slope is the coefficient of x in the equation y = mx + b.

Front

What is the significance of a negative slope?

Back

A negative slope indicates that as the independent variable (x) increases, the dependent variable (y) decreases.

How do you graph the equation y = -2x + 5?

Back

Start at the y-intercept (0, 5) and use the slope of -2 to find another point by going down 2 units and right 1 unit.

What is the meaning of the slope in a real-world context, such as hiking?

Back

In hiking, the slope indicates how steep the trail is; a steeper slope means a more challenging ascent.
