Exploring Slope Concepts in Day 2 Review

What is the slope of a line?

• The ratio of the horizontal run to the vertical rise between any two points on a line.

• The ratio of the vertical rise to the horizontal run between any two points on a line.

• The difference between the x-values of two points on a line.

• The difference between the y-values of two points on a line.

Which of the following represents the slope formula?

• y1 - y2 / x1 - x2

• y2 - y1 / x2 - x1

• x1 - x2 / y1 - y2

• x2 - x1 / y2 - y1

What does a positive slope indicate?

• The line is horizontal.

• The line is vertical.

• The line rises from left to right.

• The line falls from left to right.

What does a negative slope indicate?

• The line falls from left to right.

• The line rises from left to right.

• The line is vertical.

• The line is horizontal.

What is the slope of a vertical line?

• Undefined

• Positive

• Zero

• Negative

What is the slope of a horizontal line?

• Zero

• Undefined

• Positive

• Negative

How do you determine the slope using the slope formula?

• By adding the difference in y-values to the difference in x-values.

• By dividing the difference in x-values by the difference in y-values.

• By multiplying the difference in y-values by the difference in x-values.

• By dividing the difference in y-values by the difference in x-values.

In real-world problems, what does the slope represent?

• The total change in the independent variable.

• The sum of the dependent and independent variables.

• The rate of change between the dependent and independent variables.

• The total change in the dependent variable.

If the slope of a line is 6, what does it represent in the context of electricity cost over months?

• The cost of electricity is undefined.

• The cost of electricity remains constant.

• The cost of electricity increases by $6 each month.

• The cost of electricity decreases by $6 each month.

What does a slope of one-half represent in the context of plant growth over days?

• The plant grows 2 centimeters per day.

• The plant grows 1 centimeter per day.

• The plant grows 0.5 centimeters per day.

• The plant does not grow.
