The equation is a linear equation in two variables, so it represents a straight line. To graph it, we can rearrange it into slope-intercept form:
y = -x/2 + 9/2
This tells us that the y-intercept is 9/2 and the slope is -1/2. Starting from the y-intercept, we can go down 1 unit and right 2 units to find another point on the line, and then draw the line through those two points. The graph matches choice A.
