Multiply the equation 2x+2y=8 by 3. Does the equation have the same solution set?
1 answer:
Multiply the equation:
The solution set is the same, because multiplying both sides of an equation by a non-zero number doesn't change the solution set. In fact, if you rewrite the equation as
Multiplying this by 3 (or whatever number, for all it matters) gives
Now, a product is zero if and only if at least one of the factor is zero. So, either or
Since the first is clearly impossible, the second one must be true, which is the original equation.

Step-by-step explanation:
We want to graph:
We first graph the parent function
This parent function has x-intercept at (1,0) and it is asymptotic to the y-axis.
We then shift the graph of the parent function 3 units right, to obtain the graph of
The new x-intercept will be (4,0) and vertical asymptote will now be x=3.
