Graphing Linear Functions in Slope Intercept Form

This video tutorial provides a concise guide to graphing linear functions. It begins by explaining that f(x) and y are equivalent, and demonstrates how to rewrite functions in the slope-intercept form y=mx+b. The tutorial then details how to identify the slope and y-intercept, and use these to plot points on a graph. By applying the slope repeatedly, viewers learn to construct a linear graph. The video concludes by reiterating key concepts and encouraging viewers to subscribe for more lessons.

What does f(x) represent in a function?

• The y-intercept of the function

• The input of the function

• The output of the function

• The slope of the function

What form is used to make graphing easier?

• Quadratic form

• Slope-intercept form

• Standard form

• Point-slope form

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

• It descends from left to right

• It is vertical

• It ascends from left to right

• It is horizontal

Where does the graph of the function hit the y-axis?

• At positive 3

• At negative 2

• At positive 2

• At negative 3

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

• Draw the line

• Plot the x-intercept

• Label the axes

• Plot another point using the slope

How do you interpret the slope of -3/4 in terms of rise over run?

• Rise 4 units up, run 3 units right

• Rise 4 units down, run 3 units right

• Rise 3 units up, run 4 units right

• Rise 3 units down, run 4 units right

How can you ensure the points are aligned correctly on the graph?

• By using a ruler

• By checking the slope

• By plotting at least three points

• By measuring the distance between points

What does the graph of y = -3/4x + 2 represent?
