Front

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

Back

The slope-intercept form is given by the equation 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 represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is a proportional relationship in terms of a graph?

Back

A proportional relationship is represented by a straight line that passes through the origin (0,0).

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the slope-intercept form.

Front

What is the solution to a system of equations?

Back

The solution is the point where the graphs of the equations intersect, representing the values of x and y that satisfy both equations.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What is the formula for calculating the slope of a line given two points?

Back

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

Front

What is the significance of the point (0,0) in a proportional relationship?

Back

The point (0,0) signifies that when there is no input (x=0), the output (y) is also zero, indicating a direct proportionality.
