Question 940121
given:
the points ( {{{3}}} , {{{6}}} ) and ({{{1}}}, {{{7}}} ), 

find:

a) the distance between the points,

*[invoke Distance_Formula_for_Coordinate_Plane 3, 6, 1, 7] 


so, distance is {{{highlight(d=2.2)}}}


b) and the equation of the line passing through them.

*[invoke find_equation_of_line 3, 6, 1, 7]

 in slope-intercept form ({{{y = mx + b}}}): 

{{{highlight(y=-0.5x + 7.5)}}}
