Question

find the slope of the line passing through the given two points
1)(4,-8) and (5,-2)
2)(2a,3b)and (a,-b)
3)(a,0)and (0,b)
4)a(-1.4,-3.7)and b(-2.4,1.3)
5)a(3,-2)and b(-6,2)​

Answer 1

Answer:

We know that the slope of the line joining two points (x

1

,y

1

) and (x

2

,y

2

) is:

m=

x

2

−x

1

y

2

−y

1

Here, the given points are (4,−8) and (5,−2), therefore, the slope of the line is:

m=

x

2

−x

1

y

2

−y

1

=

5−4

−2−(−8)

=

1

−2+8

=6

Hence, the slope of the line is 6.
