In the standard (x,y) coordinate plane, 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.) 1/2 B.) -5/2 C.) -2/5 D.) -5/8 E.) It cannot be determined from the given information If line b is part of both of those intersections, then each of those points lies on line b. Use the two given points to find the slope of line b. (5,-2) , (-3,3) y2 - y1 --------- = slope {the slope formula} x2 - x1 3 - (-2) ---------- = slope {substituted coordinates into slope formula} -3 - 5 3 + 2 ------- = slope {simplified on top and bottom} -8 5 --- = slope {simplified on top} -8 D.) -5/8- Algebra House
