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 = [tex]\frac{y-y'}{x-x'}[/tex]
for points R and S m = [tex]\frac{4-1}{2-1}[/tex]
= [tex]\frac{3}{3}[/tex] = 1
Therefore, slope of the line is (1)
