Graphing Lines- Slope Intercept Form

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

In the slope-intercept form of a line, what does 'b' represent?

Back

The y-intercept of the line.

Front

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

Back

Use the formula: m = (y2 - y1) / (x2 - x1).

Front

Back

The slope (m) is 2.

Front

Back

The y-intercept (b) is 4.

Front

If a line has a slope of -5, what does this indicate about the line's direction?

Back

The line decreases as it moves from left to right.

Front

What is the slope of the line through the points (1, 2) and (3, 6)?

Back

The slope (m) is 2.

Front

Back

First, plot the y-intercept (b) on the y-axis, then use the slope (m) to find another point.

Front

What does a positive slope indicate about a line?

Back

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