Ch 6 Review Questions

Front

What is the equation that represents a linear relationship between x and y if the slope is 5 and the y-intercept is 5?

Back

y = 5x + 5

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

How do you convert the equation y + 3x = 3 into slope-intercept form?

Back

Subtract 3x from both sides to get y = -3x + 3.

Front

What is the slope of the line represented by the equation y = -2x + 4?

Back

The slope is -2.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal.

Front

What is the graphical representation of the equation y = -\frac{3}{2}x + 4?

Back

The graph is a straight line with a negative slope that crosses the y-axis at 4.

Front

What is the meaning of 'undefined slope'?

Back

An undefined slope occurs in a vertical line where x does not change.
