Answer:
see below
Step-by-step explanation:
Part A
lets go as simple as possible
x> 0 will shade the right hand side of the graph
dotted line on the y axis, shaded to the right
y <2
will shade below the line y=2
dotted line on the line y=2, shaded below
see attached graph, the red lines are dotted
Part B
C = (2,1)
is the x coordinate greater than 0 2>0
is the y coordinate less than 2 1 <2
yes it is in the shaded region
F = (3,-4)
is the x coordinate greater than 0 3>0
is the y coordinate less than 2 -4 <2
yes it is in the shaded region
Part C
y < 7x-4
the y intercept is -4
the slope is 7
draw a dotted line through -4 going up 7 and over to the right 1
shade below it
She is interested in house F,C,E
Or
(0,-4) add 7 for each increase of 1 in x
(1,3) (2,10) points E and C are less than 2,10 so they are below the line
