Calculating Slope: From Tables, Graphs, and Points

What does a positive slope indicate about the direction of a line on a graph?

• The line is horizontal.

• The line moves from left to right upwards.

• The line moves from left to right downwards.

• The line moves from right to left upwards.

How do you calculate the slope from a table of values?

• Add the change in Y to the change in X.

• Divide the change in Y by the change in X.

• Multiply the change in Y by the change in X.

• Subtract the change in X from the change in Y.

What does a negative slope indicate about a line's direction on a graph?

• The line moves upwards from left to right.

• The line is horizontal.

• The line is vertical.

• The line moves downwards from left to right.

What type of slope does a horizontal line have?

• Positive

• Negative

• Zero

• Undefined

What does an undefined slope represent?

• A horizontal line

• A line moving upwards from left to right

• A line moving downwards from left to right

• A vertical line

How is the slope represented in the equation y = mx + b?

• b

• x

• m

• y

What is the slope of a line that rises 2 units for every 1 unit it runs to the right?

• 0

• -2

• 2

• 1/2

If a line on a graph moves from left to right and downwards, what type of slope does it have?

• Negative

• Positive

• Zero

• Undefined

What is the slope of a line that does not rise or fall as it moves to the right?

• 0

• -1

• 1

• Undefined

In the slope formula (y2 - y1) / (x2 - x1), what does 'y2 - y1' represent?

• The slope of the line

• Total distance between two points

• Change in x-values

• Change in y-values
