Non-Proportional Relationships / Slope

Front

What is the definition of slope?

Back

Slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

What does 'm' represent in the equation y=mx+b?

Back

'm' represents the slope of the line.

Front

What type of slope is represented by a line that goes down from left to right?

Back

Negative slope.

Front

What type of slope is represented by a line that goes up from left to right?

Back

Positive slope.

Front

What does 'b' represent in the equation y=mx+b?

Back

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

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of -5/3, what does this indicate about the line's steepness?

Back

The line is steep and descends from left to right.

Front

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

Back

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

Front

In the equation y = 40x + 75, what does the 40 represent?

Back

The 40 represents the rate of change or slope of the line.
