Slope/Intercept Flashcard

Front

What is the slope of a line that rises from left to right?

Back

Positive Slope

Front

What is the slope of a line that falls from left to right?

Back

Negative Slope

Front

What is the slope of a horizontal line?

Back

0 (Zero) Slope

Front

What is the slope of a vertical line?

Back

Undefined Slope

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

Convert the equation 2x + 3y = 6 into slope-intercept form.

Back

y = -2/3x + 2

Front

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

Back

The y-intercept, where the line crosses the y-axis.

Front

If a line has a slope of 4, what does this mean?

Back

For every 4 units it rises, it moves 1 unit to the right.

Front

What is the equation of a line with a slope of -1 that crosses the y-axis at 3?

Back

y = -x + 3

Front

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

Back

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