Review: Slopes and Slope Intercept Form of a Line

Front

What is the slope in the equation y=mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

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

Back

The y-intercept, which is the point where the line crosses the y-axis.

Front

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

Back

Front

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

Back

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

Front

What type of slope does a line that rises from left to right have?

Back

Positive slope.

Front

What type of slope does a line that falls from left to right have?

Back

Negative slope.

Front

What does a slope of zero indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

If the slope of a line is -2, what does this indicate about the line's direction?

Back

The line descends from left to right.

Front

In the equation y=-5x + 7, what is the slope?

Back
