Question

Find the slope of the line joining the two given points
(4.-8) and (5.-2)
(2a, 3b) and (a. -b)
(iv) (a,0) and (0,b)
(v) A(-1.4.-3.7), B(-2.4.1.3)
(vi) A(3,-2), B(-6,-2)
(0,0) and (V3.3)
A[-3½,3],B[-7,2½]
(vii) A(0,4), B(4,0)​

Answer 1

Answer:

2a,3b and a.-b .................................

Answer 2

Answer:

4,8 and 5,-2

slope = (-2-8)/(5-4)

= - 10/1= - 10

2a,3b and a,-b

slope = (-b -3b)/(a-2a) = (-4b)/-(a) = 4b/a
