Finding Slope through Various Representations

What does the slope of a line represent?

• The steepness or angle of a line

• The vertical change between two points

• The horizontal change between two points

• The length of the line

What is the slope of a line that is completely horizontal?

• Undefined

• Negative

• Zero

• Positive

What does a negative slope indicate about the direction of the line?

• The line is vertical

• The line is falling from left to right

• The line is horizontal

• The line is rising from left to right

What type of slope does a vertical line have?

• Zero

• Positive

• Negative

• Undefined

How do you calculate the slope from a graph?

• Identify two points and divide the change in y by the change in x

• Divide the change in x by the change in y

• Multiply the coordinates of two points

• Subtract the x-coordinates and divide by the difference in y-coordinates

What is the formula for calculating slope using coordinates?

• (y1 - y2) / (x1 - x2)

• x2 - x1 + y2 - y1

• (y2 - y1) / (x2 - x1)

• (x2 - x1) / (y2 - y1)

When using a table to calculate slope, what is crucial to maintain?

• The subtraction of the first point from the second

• The order of x and y coordinates

• The multiplication of coordinates

• The addition of all x and y values

What is the slope if the rise is 4 and the run is -5?

• -1.25

• 0.8

• -0.8

• 1

How do you handle a slope calculation when the denominator is zero?

• The slope is undefined

• The slope is one

• The slope is zero

• The slope is infinite

In function notation, what does 'f of 0 equals 10' suggest about the coordinates?

• (10, 10)

• (0, 0)

• (0, 10)

• (10, 0)
