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 Ask Algebra House Comments are closed.
