Problema Solution
given the slope of a line through the points (x,3) and (4,5) is 1/3. Find x
Answer provided by our tutors
The slope m of the line through the points (x1, y1) and (x2, y2) is given by:
m = (y2 - y1)/(x2 - x1)
In our case m = 1/3, x1 = x, y1 = 3, x2 = 4, y2 = 5
1/3 = (5 - 3)/(4 - x)
(5 - 3)/(4 - x) = 1/3
