Graphing Linear Functions Quiz

What is the first step in graphing a linear function?

• Plotting random points

• Identifying the x-intercept

• Rewriting the function in terms of y

• Finding the slope

What do f(x) and y represent in a function?

• The input of the function

• The slope of the function

• The output of the function

• The x-intercept of the function

In the slope-intercept form y = mx + b, what does 'm' represent?

• The y-intercept

• The slope

• The x-intercept

• The output

What is the y-intercept in the function y = -3/4x + 2?

• -3/4

• 4

• 2

• -3

How do you interpret a negative slope in a graph?

• The line is horizontal

• The line descends from left to right

• The line ascends from left to right

• The line is vertical

What is the next step after plotting the y-intercept?

• Plotting the x-intercept

• Drawing the line

• Finding the slope

• Using the slope to plot additional points

If the slope is -3/4, how do you plot the next point from the y-intercept?

• Move up 3 units and right 4 units

• Move down 3 units and left 4 units

• Move down 3 units and right 4 units

• Move up 3 units and left 4 units

What should you do if you want to plot points on the left side of the y-intercept?

• Move right 4 units and down 3 units

• Move left 4 units and up 3 units

• Move left 4 units and down 3 units

• Move right 4 units and up 3 units

What does it mean if all your plotted points are aligned?

• You can construct the line

• The slope is incorrect

• You have made a mistake

• The y-intercept is wrong

What is the key takeaway about y and f(x) in the context of graphing linear functions?

• They are not related

• They are both outputs

• They are both inputs

• They represent different things
