Question

PLEASE HELP!!! The coordinate plane below represents a city. Points A through F are schools in the city.

graph of coordinate plane. Point A is at negative 3, negative 4. Point B is at negative 4, 3. Point C is at 2, 2. Point D is at 1, negative 2. Point E is at 5, negative 4. Point F is at 3, 4.

Part A: Using the graph above, create a system of inequalities that only contain points C and F in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points)

Answer 4

PART A:
Since C and F are in the first quadrant (both x and y positive), we could create the following two inequalities:
x > 0
y > 0

The solution set to that would be all points above the x-axis and to the right of the y-axis.

PART B:
To verify if a point is in the solution set, just check that the point (x,y) satisfies the system of inequalities. In our example:
C is the point (2,2)
x = 2 --> 2 > 0
y = 2 --> 2 > 0

F is the point (3,4)
x = 3 --> 3 > 0
y = 4 --> 4 > 0

PART C:
Graph the line y = -2x + 2. That will be a line that has a y-intercept of 2 and a slope of -2. Then shade *below* that line (we shade below because it is y < ...). The schools that will be in the shaded region are B, A and D.
