Question

A straight line passes through the points (5, j) and (j, 6). The slope of the line is 2/3 . What is the value of j

Answer 1

Step-by-step explanation:

Given, X1 =5, Y1 =j, X2 =j, Y2 =6

Slope =(Y2 - Y1 )/(X2 - X1)

==> 2/3 = (6 - j)/(j - 5)

==> 2(j - 5) = 3(6 - j)

==> 2j - 10 = 18 - 3j

==> 2j + 3j = 18 +10

==> 5j = 28

==> j = 28/5

==> j = 5.6 Ans.
