Answer

The solution to the system is \( (-2, 2) \).

Solution

To graph the system of equations and find its solution, we can follow these steps: 1. Graph the first equation \( -2x + y = 6 \) on a coordinate plane. 2. Graph the second equation \( y = \frac{1}{2}x + 3 \) on the same coordinate plane. 3. Find the point of intersection of the two lines, which will be the solution to the system of equations. Let's start by graphing the first equation \( -2x + y = 6 \). We can rewrite this equation in slope-intercept form as \( y = 2x + 6 \). The slope of this line is 2, and the y-intercept is 6. Next, let's graph the second equation \( y = \frac{1}{2}x + 3 \). The slope of this line is 1/2, and the y-intercept is 3. Now, we need to find the point of intersection of these two lines. To do this, we can set the two equations equal to each other and solve for x. Setting the two equations equal to each other, we have: \[ 2x + 6 = \frac{1}{2}x + 3 \] Solving for x, we get: \[ 2x - \frac{1}{2}x = 3 - 6 \] \[ \frac{3}{2}x = -3 \] \[ x = -2 \] Substituting x = -2 into one of the original equations, we can find the corresponding value of y. Let's use the first equation: \[ -2(-2) + y = 6 \] \[ 4 + y = 6 \] \[ y = 2 \] Therefore, the solution to the system of equations is \( (-2, 2) \).

Extra Insights

To graph the system, start with the first equation, \(-2x + y = 6\). Rearranging it gives \(y = 2x + 6\). This is a linear equation with a slope of 2 and a y-intercept of 6. Plot the y-intercept (0, 6) and use the slope to find another point (for instance, from (0, 6), move down 2 and right 1 to (1, 4)). Next, for the second equation, \(y = \frac{1}{2}x + 3\), it has a slope of \(\frac{1}{2}\) and a y-intercept of 3. Plot the y-intercept (0, 3), then move up 1 and right 2 to find another point (2, 4). Now, draw the lines for both equations. The solution to the system is the point where the lines intersect. From the graph, you can see both lines intersect at (2, 4). Therefore, the solution to the system is \( (2, 4) \).
