Front

What is the slope of a line represented by the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x. It indicates the steepness and direction of the line.

Front

What does it mean if a slope is undefined?

Back

An undefined slope occurs when a line is vertical, meaning there is no change in x while y changes.

Front

Back

n = -5.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.

Front

What is the y-intercept in the equation of a line y = mx + b?

Back

The y-intercept (b) is the point where the line crosses the y-axis, occurring when x = 0.

Front

Back

x = -6.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect.

Front

What does the point (1, -1) represent in a coordinate plane?

Back

It represents a location where x = 1 and y = -1.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By + C = 0, where A, B, and C are constants.
