What is the general form of a linear equation?

Back

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

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

How do you determine if a relationship is proportional?

Back

A relationship is proportional if the ratio of y to x is constant for all values.

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and there is no change in y as x changes.

What is the y-intercept in the equation y = x + 5?

Back

The y-intercept is 5, which is the value of y when x is 0.

How can you find the slope from a slope triangle?

Back

The slope can be found by dividing the rise (change in y) by the run (change in x) of the triangle.

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio between y and x, while non-proportional relationships do not.

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.

How do you graph a linear equation?

Back

To graph a linear equation, plot the y-intercept on the y-axis and use the slope to find another point.
