Math Problem Statement
Solution
In the image you shared, we are tasked with solving the system of linear equations by graphing:
Let's break down the process:
-
Rewrite each equation in slope-intercept form (y = mx + b):
- For the first equation , solve for :
- For the second equation , solve for :
-
Graph the equations:
- The first equation has a slope of and a y-intercept of .
- The second equation has a slope of and a y-intercept of .
-
Interpret the graph: From the graph in the image, it appears that the two lines intersect at a point, which indicates a single solution. The coordinates of this point will give us the ordered pair solution.
-
Conclusion: Based on the graph, the lines intersect at a specific point, confirming there is one unique solution.
Answer: The solution of the system is the ordered pair of the intersection point.
Would you like to calculate or analyze the exact solution of the intersection, or do you have any other questions? Here are some follow-up questions:
- What is the exact intersection point of the two lines?
- How can you solve a system of linear equations algebraically?
- What happens if the lines are parallel or coincident?
- How would you graph systems of equations with more than two variables?
- How can you check if your graphing solution is correct?
Tip: Always double-check your graph for accuracy by ensuring both lines pass through their respective y-intercepts and follow the correct slope.
