Math Problem Statement
Solution
The system of equations given in the image is:
You are asked to solve this system graphically. To do this, let's find the points where the two lines intersect.
Step 1: Graph the first equation
This is a straight line with:
- Slope (meaning it rises 2 units for every 1 unit increase in ).
- Y-intercept at .
You can plot this line by starting at and using the slope to move up 2 units and 1 unit to the right to plot additional points.
Step 2: Graph the second equation
This is also a straight line with:
- Slope (meaning it falls 1 unit for every 1 unit increase in ).
- Y-intercept at .
Plot this line starting at and moving down 1 unit and 1 unit to the right to mark more points.
Step 3: Find the Intersection Point
The intersection of these two lines gives the solution to the system of equations. Solving algebraically:
Set .
Substitute into one of the original equations, say :
Thus, the solution is , . The lines intersect at the point .
Do you want more details or have any further questions? Here are some related questions to deepen your understanding:
- How can you verify if the solution satisfies both equations?
- What happens if two lines are parallel in a system of equations? How is the solution affected?
- Can you solve this system using substitution or elimination, and how does the solution compare?
- What does the slope of a line tell you about how it behaves on a graph?
- How would the graph look if the lines were perpendicular?
Tip: When graphing lines, always pay attention to the slope and y-intercept, as they determine the position and steepness of the line.
