Final Exam Review day 3

Front

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

Back

m = -1, b = 4

Front

How do you calculate slope using a graph?

Back

Slope is calculated as rise over run.

Front

In the slope-intercept form (y = mx + b), what does 'm' represent?

Back

The slope (rate of change).

Front

What is the slope of the line with the equation y = -\frac{3}{2}x + 4?

Back

m = -\frac{3}{2}.

Front

If m = 3 and b = 6, what is the slope-intercept equation?

Back

y = 3x + 6.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of 'b' when x = 0.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

How can you identify the slope from a graph?

Back

The slope can be identified by counting the rise (vertical change) over the run (horizontal change).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
