In the standard (x,y) coordinate plane, lines a and c intersect at point (5,-2). Lines b and c intersect at point (-3,3). What is the slope of line b?

A.) 1/2

B.) -5/2

C.) -2/5

D.) -5/8

E.) cannot be determined

**To find the slope of line b, find the slope of the line passing through the points (5,-2) and (-3,3).**

y2 - y1

---------- = slope of a line

x2 - x1

The given points are the coordinates (x1,y1) and (x2,y2).

(5,-2) and (-3,3)

3 - (-2)

--------- = slope of the line {substituted coordinates into slope formula}

-3 - 5

5

---- = slope {subtracted on top and bottom}

-8

**D.) -5/8**
