Front

What is the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

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

Back

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

Front

How do you find the greatest common factor (GCF) of two or more terms?

Back

The GCF is the largest factor that divides all the terms without leaving a remainder.

Front

What is the profit equation for a business?

Back

Profit (P) can be calculated using the formula: P = Revenue - Costs.

Front

How do you solve for n in the equation P = 5n - 200?

Back

Rearrange the equation to find n: n = (P + 200) / 5.

Front

What does it mean for a function to be linear?

Back

A linear function is one that graphs to a straight line, represented by the equation y = mx + b.

Front

What is the significance of the y-intercept in a linear equation?

Back

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

Front

How do you determine if a line is increasing or decreasing?

Back

A line is increasing if the slope is positive and decreasing if the slope is negative.

Front

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

Back

The formula is m = (y2 - y1) / (x2 - x1).

Front

What is the relationship between the slope and the steepness of a line?

Back

A larger absolute value of the slope indicates a steeper line.
