How to graph an identity function

The video tutorial explains how to graph equations in the form Y=MX+B without converting to standard form. It emphasizes understanding the slope and intercept for graphing and suggests using a table of X and Y coordinates if stuck. The tutorial demonstrates graphing by identifying the slope and intercept, and provides a step-by-step guide on plotting points using the slope. It also highlights the importance of recognizing patterns in graphing and offers practical tips for ensuring accuracy.

What is the advantage of having an equation in MX plus B form?

• It is only useful for quadratic equations.

• It requires additional calculations.

• It makes the equation more complex.

• It allows for easy identification of the slope and intercept.

What should you do if you are unsure about how to graph an equation?

• Ignore the slope.

• Convert it to a quadratic equation.

• Create a table of X and Y coordinates.

• Use a calculator.

In the equation Y = MX + B, what does the 'B' represent?

• The origin

• The Y-intercept

• The slope

• The X-intercept

If the Y-intercept is zero, where does the line cross the Y-axis?

• At the origin

• It does not cross the Y-axis

• At Y = 1

• At Y = -1

How can you use the slope to plot the graph?

• Ignore the slope and draw a straight line.

• Only move vertically.

• Only move horizontally.

• Move down and to the right or up and to the left following the slope.
