What is the equation of a line in slope-intercept form?

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

How do you determine the y-intercept from a linear equation?

Back

Front

What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph. It can be described by a linear equation.

Front

How can you find the distance traveled based on a graph?

Back

To find the distance traveled based on a graph, locate the point on the graph that corresponds to the time or condition in question and read the value on the distance axis.

Front

What does it mean if two lines on a graph are parallel?

Back

If two lines on a graph are parallel, it means they have the same slope but different y-intercepts, indicating that they never intersect.

Front

What is the significance of the x-axis and y-axis in a graph?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable. Together, they help visualize the relationship between the two variables.

Front

How do you interpret the intersection point of two lines on a graph?

Back

The intersection point of two lines on a graph represents the values of the variables where both equations are satisfied simultaneously.

Front

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

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship between the two variables.
