Question

Find the slope of each set of points.

a.) 4, 3 and -3, 4 b.) -2, 0 and (8, -4)

Answer 1

1. (4, 3) and (-3, 4) has Slope = -1/7

2.(-2, 0) and (8, -4) has Slope = -2/5

Explanation:

If two such points (a,b) and (c,d) are given, then the slope S is given as:

`S = ((d-b)/(c-a) )`

Now here, the given set of points are:

1. (4, 3) and (-3, 4)

Here, the slope S =
`((4-3)/(-3-4)) = ((1)/(-7)) = -((1)/(7))`

⇒ S = -1/7

1. (-2, 0) and (8, -4)

Here, the slope S =
`((-4-0)/(8-(-2))) = ((-4)/(10)) = -((2)/(5))`

⇒ S = -2/5
