Question 938262: The points (3, h) and (7,5) lie on a line with slope 6. Find the missing coordinate h
Answer by MathLover1(20850)   (Show Source):
You can put this solution on YOUR website! You get slope  by subtracting your first  coordinate by your second  coordinate, and putting that over your first coordinate subtracted from your second  coordinate.
 ...
given the points
( ,  ) = ( ,  ) and
( ,  ) =( , })
and a slope 
so,
 ...solve for
so, the point is (,  )
now to check our work, we can find equation of this line with a slope and passing through one of the given points; let use this one (, )
let check if both points lie on this line:
