Fill in the Blank

A hypothesis can often be written as an "If ___, then ___" statement.

Fill in the Blank

In this experiment the ____________ variable is how he decided to learn names. The ____________ variable is how many days it took to learn names. One example of a ____________ that he should have involves the number of students in each class. Mr. Monk's ____________ was that if he played name games that he would learn the names fastest.

Multiple Choice

• Pie chart

• Scatter plot

Open Ended

Explain how the concepts of independent and dependent variables are important when designing an experiment and representing data on a graph.

Multiple Select

Which of the following are important components of a line graph according to the lesson?

• Title

• Labels with units

• Variables on correct axes

• Intervals representing the same value

Multiple Choice

What does the 'm' represent in the linear equation y = mx + b?

• The slope of the line

• The y-intercept

• The x-value

• The variable

Multiple Choice

What is the slope of the line shown in the graph, and what does it represent?

• 2/3, representing the rate of change of y with respect to x

• 3/2, representing the rate of change of x with respect to y

• 1, representing a constant increase

• 0, representing no change

Multiple Choice

If the slope of a line is negative, how would the line appear on a graph?

• It would slope downwards from left to right

• It would slope upwards from left to right

• It would be horizontal

• It would be vertical

Fill in the Blank

Multiple Select

Which of the following are necessary steps to write the equation of a line in slope-intercept form?

• Find the y-intercept

• Calculate the slope

• Multiply the slope by the y-intercept

• Combine the slope and y-intercept in the form y = mx + b

Open Ended
