Question

The set of points R(-1, 1), S(2, 4), T(6, 8) are collinear and the line has a slope of _____.

Answer 1

1

Explanation:

Answer 2

slope of the line is (1)

Explanation:

Set of points are R( -1, 1 ) S( 2, 4 ) and T( 6, 8 )

We have to find the slope of the line for which these points are collinear.

Since we know slope m =
`(y-y')/(x-x')`

for points R and S m =
`(4-1)/(2-1)`

=
`(3)/(3)` = 1

Therefore, slope of the line is (1)
