Estimating Solutions of Systems

Question 7 • (AG Q4) Keystone Algebra 1 Block: 25-26 (DDiamond)

As a computer technician, Andre makes $20 per hour to diagnose a problem and $25 per hour to fix a problem. He works fewer than 10 hours per week, but wants to make at least $200 per week. The inequalities 20x + 25y ≥ 200 andx + y < 10 represent the situation. Which is true of the graph of the solution set? Check all that apply.The line 20x + 25y ≥ 200 has a positive slope and a negative y-intercept.The line x + y < 10 has a negative slope and a positive y-intercept.The line representing 20x + 25y ≥ 200 is solid and the graph is shaded above the line.The line representing x + y < 10 is dashed and the graph is shaded above the line.The overlapping region contains the point (4, 5).

Answer
A
The line 20x + 25y ≥ 200 has a positive slope and a negative y-intercept.
B
The line x + y < 10 has a negative slope and a positive y-intercept.
C
The line representing 20x + 25y ≥ 200 is solid and the graph is shaded above the line.
D
The line representing x + y < 10 is dashed and the graph is shaded above the line.
E
The overlapping region contains the point (4, 5).
