Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line. It can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis. It is the value of y when x = 0.

Front

How do you find the slope from two points?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

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

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for a function to be proportional?

Back

A function is proportional if it can be expressed in the form y = kx, where k is a constant. This means that as x increases, y increases at a constant rate.

Front

How do you interpret a scatterplot?

Back

A scatterplot shows the relationship between two variables. The pattern of points can indicate whether there is a positive, negative, or no correlation between the variables.

Front

What is the profit formula?

Back

The profit can be calculated using the formula: Profit = Revenue - Costs.

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 write an equation from a table of values?

Back

To write an equation from a table, identify the relationship between the x and y values, determine the slope, and use a point to find the y-intercept.
