Graphing Linear Functions Quiz

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

• The x-intercept of the function

• The output of the function

• The slope of the function

• The input of the function

What is the first step in graphing a linear function in slope-intercept form?

• Identify the slope

• Find the x-intercept

• Plot the y-intercept

• Rewrite the function in terms of y

If the slope of a line is -3/4, what does the negative sign indicate?

• The line ascends from left to right

• The line is vertical

• The line descends from left to right

• The line is horizontal

How do you plot a new point using the slope -3/4 from a given point?

• Move up 3 units and left 4 units

• Move down 3 units and right 4 units

• Move up 3 units and right 4 units

• Move down 3 units and left 4 units

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

• Go left 4 units and up 3 units

• Go right 4 units and up 3 units

• Go right 4 units and down 3 units

• Go left 4 units and down 3 units
