Ur graph.....u have a line that has a y int of -2....it has a slope of 3....it has a solid line...so there is no equal sign...it is shaded above the line, so it is greater then.....y > = 3x - 2
u have another line that has a y int of 2....it has a slope of -1/2....it has a solid line...so there is an equal sign in the problem...it is shaded below the line...so it is less then....
y < = -1/2x + 2
1/2x + y < = 2...multiply by 2
x + 2y < = 4
so ur answer is : y > = 3x - 2 and x + 2y < = 4...the 2nd one
1. k = 2<span>2.5</span><span>
2. xy=k
thats what i got</span>
(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1
4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12
x=-3
