I put in a graph and the equation
y<2x-5
y>-3x+1

Step-by-step explanation:
The center of this circle is at (0, 0) because there are no identifiers in front of the x and y values. After you graph the circle, you will see that (3, -1) is on the circle.
f(x, y) = 4x + 7y - 6
substitute x=5 and y=-5
f(5,-5) = 4(5) + 7(-5) - 6
f(5,-5) =20-35-6
= -15-6
=-21
