Math Problem Statement
Solution
The image shows a system of two linear equations that need to be graphed and solved. The equations are:
To solve these equations graphically:
-
Plot the first equation :
- The y-intercept is (point ).
- The slope is , so from , move down 2 units and 1 unit to the right to get another point .
-
Plot the second equation :
- The y-intercept is (point ).
- The slope is , so from , move up 6 units and 1 unit to the right to get another point .
-
Find the intersection of the two lines:
- The lines intersect at . This is the solution to the system of equations.
