To graph the system of linear equations, we need to plot the points that satisfy both equations and see where they intersect.

Starting with the first equation y = x + 3, we can find several points that satisfy this equation by selecting different values for x and calculating the corresponding values for y. For example, when x = 0, y = 0 + 3 = 3. So, one point on the graph is (0, 3). Similarly, when x = 1, y = 1 + 3 = 4. So, another point is (1, 4).

For the second equation -4x + 4y = 28, let's rewrite it in terms of y to find points on the graph. Divide both sides by 4 to get y = x + 7. Again, we can choose different x values to find corresponding y values. When x = 0, y = 0 + 7 = 7. So, one point on the graph is (0, 7). When x = 1, y = 1 + 7 = 8. So, another point is (1, 8).

Now, let's plot these points on a graph:

By connecting the dots, we can see that the lines intersect at (1, 4).

This tells us that the solution to the system of linear equations is x = 1 and y = 4.

Sure! When graphing the system of linear equations, we can see that the two lines intersect at the point (4, 7). This indicates that the solution to the system is x = 4 and y = 7.
so this is the answer??
