Find the prime factors of the numbers

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
