Slope Given Two Points

Front

What is the slope of a vertical line?

Back

Undefined

Front

What is the slope of a horizontal line?

Back

0

Front

How do you calculate the slope given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

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

Back

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

Front

If the slope of a line is 4/3, what does this mean?

Back

For every 3 units moved horizontally, the line rises 4 units vertically.

Front

What is the slope of the line that passes through the points (2, 5) and (-3, 5)?

Back

0, because the y-coordinates are the same.

Front

What is the equation of a vertical line that passes through x = 3?

Back

x = 3.

Front

What is the slope of a line parallel to the x-axis?

Back

0.
