Question

Graphing and functions

Answer 1

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

Part B: Explain how to verify that the points A and E are solutions to the system of inequalities created in Part A. (3 points)

Part C: William can only attend a school in his designated zone. William's zone is defined by y < -x - 1. Explain how you can identify the schools that William is allowed to attend. (2 points)

Answer 2

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

Answer 3

Answer 4

y<x can contain both points A and E
Need another one that overlaps this region

Answer 5

8x-3y>12 works 1 think

Answer 6

but hold on a second, point B would also be contained in Y<x , so we cant use that one

Answer 7

Only the overlapping shaded regions can have only A and E, if that makes sense.

Answer 8

so 1 think y<x still works

Answer 9

yes, meaning no other points can be in the shaded region, just A and E

Answer 10

B(-3,-4)

-4<-3 True it is in the region, cant be used

Answer 11

in the OVERLAPPING shaded rejoin, unless 1'm reading it wrong which is a possiblity.

Answer 12

right on, so let the first line be Y<X

Answer 13

does my previous inequality fit?

Answer 14

umm

Answer 15

8x-3y>12

Answer 16

yes it does

Answer 17

just had to try a couple points into it and make sure

Answer 18

how should 1 explain how to graph it?
