Consider the equation
Predict what the graph of this equation looks like. Justify your answer.
Are there any exponents? What does this mean?
Solve the equation for y and graph the equation.
Get y by itself.
Explain clearly how to find the x- and y-intercepts.
The x-intercept is the point where
The y-intercept is the point where
Which form of the equation is best for finding the x- and y-intercepts quickly? Why?
It’s easier to use the given, standard form of the equation to find the intercepts quickly because there is minimal rewriting involved.
Find the x- and y-intercepts of
. Then use the intercepts to sketch a graph quickly.
to find the y-intercept, and to find the x-intercept.
x-intercept: (−9, 0)
y-intercept: (0, 6)
