What does the slope of a line represent in a graph of a linear equation in two variables?

• The maximum value of the dependent variable

• The rate at which the dependent variable changes with respect to the independent variable

• The intersection point of the line with the y-axis

• The intersection point of the line with the x-axis

Consider a graph of a linear equation showing the relationship between temperature in Celsius and Fahrenheit. If the slope of the line is positive, what does this indicate about the relationship between Celsius and Fahrenheit temperatures?

• As the temperature in Celsius decreases, the Fahrenheit temperature increases

• There is no relationship between Celsius and Fahrenheit temperatures

• As the temperature in Celsius increases, the Fahrenheit temperature decreases

• As the temperature in Celsius increases, the Fahrenheit temperature also increases

If a line in a graph has a slope of 2, what does this mean?

• For every 1 unit increase in the x-axis, the value of y decreases by 2 units

• For every 1 unit increase in the x-axis, the value of y increases by 2 units

• The line crosses the y-axis at the point (0, 2)

• The line crosses the x-axis at the point (2, 0)

In a graph showing the relationship between the number of hours studied and the score on a test, if the line has a steep slope, what does this indicate about the relationship between hours studied and test score?

• There is a weak relationship between hours studied and test score

• There is a strong positive relationship; scores increase significantly with more hours studied

• There is a strong negative relationship; scores decrease with more hours studied

• The number of hours studied has no effect on the test score

If a graph of a linear equation relating the amount of fertilizer used to the height of a plant has a negative slope, what does this tell you?

• Using more fertilizer always decreases the height of the plant

• Using more fertilizer has no effect on the height of the plant

• Using more fertilizer increases the height of the plant

• The relationship between fertilizer use and plant height cannot be determined from the slope alone
