Graphing Lines

Front

What are the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

Can the graph of a linear function be shaped like a 'u'?

Back

False

Front

Is the graph of a linear function always horizontal?

Back

False

Front

How do you find the slope of a line that passes through (1, -19) and (-2, -7)?

Back

The slope is -4.

Front

If m = 1/2 and b = -4, what is the slope-intercept equation?

Back

y = 1/2x - 4.

Front

What is the definition of slope in a graph?

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What does the 'b' represent in the slope-intercept form of a linear equation?

Back

The 'b' represents the y-intercept, where the line crosses the y-axis.

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 is the slope of a line that is vertical?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is 0.
