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

Answer:

slope of the line is (1)

Step-by-step 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 = $\frac{y-y'}{x-x'}$

for points R and S       m = $\frac{4-1}{2-1}$

                                        = $\frac{3}{3}$ = 1

Therefore, slope of the line is (1)
