Get the app Socratic and then take a pic, it will explain it better than anybody on here can
Y = 5 - 4x
5 - 4x = x^2 - 2x - 19
0 = x^2 + 2x -24
0 = (x + 6)(x - 4)
Therefore x = -6 (Given) or 4
x = 4, y = -9
(4,-9) is the other solution
The area of a circle with radius of 13 millimeters is A≈530.93A=πr2=π·132≈530.92916
