In the xy-plane, if lines a and b intersect at point (5,–2) and lines

Question

In the xy-plane, if lines a and b intersect at point (5,–2) and lines b and c intersect at point (–3,3), what is the slope of line b ?

(A) −5/2
(B) −5/8
(C) −2/5
(D) 1/2
(E) It cannot be determined from the information given.

Line b passes through the points (5,-2) and (3,-3).

the slope of the line is given by  m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - (-2)}{3 - 5} = \frac{-1}{-2} = \frac{1}{2}
