Math Problem Statement
Complete the ordered pairs. Then graph the equation by plotting the points and drawing a line through them.
y = -x - 5
(0, ), ( , 0), (2, )
Solution
Let's first complete the ordered pairs using the equation .
-
For (0, __): Substitute into the equation to find : So, the ordered pair is .
-
For (__, 0): Substitute into the equation to find : So, the ordered pair is .
-
For (2, __): Substitute into the equation to find : So, the ordered pair is .
Final Ordered Pairs:
Graphing the Equation:
- Plot the points , , and on a coordinate plane.
- Draw a straight line through the points to represent the equation .
Would you like me to graph the equation for you?
Here are some follow-up questions based on this problem:
- What is the slope of the line represented by the equation ?
- How would the graph change if the equation were ?
- What are the intercepts of the line in the original equation?
- How would you find the ordered pairs for and ?
- How can you verify that a point lies on the line defined by ?
Tip: The slope of a line is key in understanding its steepness and direction. Here, the slope is , meaning the line falls as you move from left to right.
