Graphing Proportional Relationships and Slope

What is the first step in graphing proportional relationships from an equation?

• Calculating the unit rate

• Finding the y-intercept

• Drawing the x-axis

• Identifying the slope

In the equation y = 3x for the bean plant, what does the number 3 represent?

• The initial height of the plant

• The number of weeks

• The growth rate per week

• The total height after 3 weeks

How many centimeters does the bean plant grow after 2 weeks?

• 6 centimeters

• 3 centimeters

• 9 centimeters

• 12 centimeters

What is the unit rate in the equation y = 3x?

• 4

• 3

• 2

• 1

What is the equation used to represent the growth of the radish plant?

• y = 3x

• y = 5/6x

• y = 2x

• y = 1/2x

Why is it difficult to plot 5/6 of a centimeter on the graph?

• Because it is a very small value

• Because it is not a whole number

• Because it is greater than 1

• Because it is less than 1

What does the 'rise' represent in the slope of a fraction?

• The horizontal distance

• The vertical distance

• The initial point

• The total distance

How do you plot the point for the radish plant's growth using rise over run?

• Go up 5 centimeters and over 6 weeks

• Go up 3 centimeters and over 3 weeks

• Go up 6 centimeters and over 5 weeks

• Go up 1 centimeter and over 1 week

What is another way to interpret the growth of the radish plant?

• It grows 5 centimeters every 6 weeks

• It grows 6 centimeters every 5 weeks

• It grows 6 centimeters every 6 weeks

• It grows 5 centimeters every 5 weeks

What is the benefit of using rise over run for graphing fractional slopes?

• It simplifies the plotting process

• It makes the graph more accurate

• It changes the slope value

• It eliminates the need for a graph
