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 lines a and b intersect at point (5,2) and lines b and c intersect at point (3,3), then
line b passes through the points (5,2) and (3,3). Find the slope of line b. y2  y1  = slope x2  x1 Points (5,2) and (3,3) are (x1,y1) and (x2,y2). 3  (2)  = slope {substituted given coordinates into slope formula} 3  5 3 + 2  = slope {simplified in numerator and denominator} 2 1  = slope {added in numerator} 2 slope = 1/2 {simplified} A.) 1/2 Ask Algebra House Comments are closed.
