Graphing Slope-Intercept Form

Front

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

Back

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

Front

What does the variable 'm' represent in the equation y = mx + b?

Back

The variable 'm' represents the slope of the line.

Front

What does the variable 'b' represent in the equation y = mx + b?

Back

The variable 'b' represents the y-intercept of the line.

Front

How do you find the y-intercept from the equation y = -4x - 5?

Back

The y-intercept is -5, which is the value of b in the equation.

Front

What is the slope of the line represented by the equation y = 0x + 3?

Back

The slope is 0, indicating a horizontal line.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

What is the significance of the y-intercept in graphing a line?

Back

The y-intercept indicates where the line crosses the y-axis, helping to start graphing the line.

Front

If a line has an undefined slope, what does that mean?

Back

An undefined slope means the line is vertical.

Front

How can you determine if a line is horizontal from its equation?

Back

If the slope (m) is 0, the line is horizontal.
