Slope and Y-Intercept

Front

What is the slope of the line represented by the equation y = 2/3x - 3?

Back

2/3

Front

What is the y-intercept of the equation y = 2/3x - 3?

Back

-3

Front

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

Back

Slope = (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 formula for the slope-intercept form of a line?

Back

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

Front

If the slope of a line is 4, what is the rise if the run is 1?

Back

Rise = 4 (since slope = rise/run)

Front

What is the slope of the line represented by the equation y = 4x + 3?

Back

4

Front

What is the definition of y-intercept?

Back

The y-coordinate where the line crosses the y-axis.

Front

If a line has a slope of 0, what does that mean?

Back

The line is horizontal.
