Answer 1

Sorry, both answers are not correct.

The slope between two points P1(x1,y1) and P2(x2,y2) is given by the formula:
slope = (y2-y1)/(x2-x1)

Take the case of P1(4,5), P2(2,3)
Slope of P1-P2 = (3-5)/(2-4) = -2/-2 = 1

Try to work out along these lines for the two given problem, and post your solution for rechecking.

Answer 2
