Equation:
a. Solve the equation for and sketch the graph.
.........move to the right
......divide both sides by

graph:

b. Multiply the equation by , and then solve
for.
How does the graph of this equation compare with the graph of the original equation? Explain your answer.

the graph of this equation is same as the graph of the original equation; we did multiply equation by , but in order to solve it for we needed to divide by too
or, if we use this property our equation will not change
