Answer:
{-2, 1}
Step-by-step explanation:
Make the fractions have a common denominator.
Now that both sides of the equation have a common denominator, you can cancel out the denominators.
Now, set the equation equal to zero and factor.
The y-values are {-2, 1}
Answer:
d) one solution; (4, 1)
Step-by-step explanation:
It often works well to follow problem directions. A graph is attached, showing the one solution to be (4, 1).
_____
You know there will be one solution because the lines have different slopes. Each is in the form ...
y = mx + b
where m is the slope and b is the y-intercept.
The first line has slope -1 and y-intercept +5; the second line has slope 1 and y-intercept -3. The slope is the number of units of "rise" for each unit of "run", so it can be convenient to graph these by starting at the y-intercept and plotting points with those rise and run from the point you know.
