Answer:
(x, y) = (2, 2)
Step-by-step explanation:
The graph is attached.
Both equations are in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept b
The graph of the first equation intersects the y-axis at +3, and has a slope (rise/run) of -1/2. That is, it decreases 1 unit for each 2 units to the right.
The graph of the second equation intersects the y-axis at -4, and has a slope of +3. It will increase 3 units for each unit to the right.
The point of intersection of the graphed lines is (2, 2).
The solution is (x, y) = (2, 2).
