Find the value of x so that the line passes through the points (2,3) and (x,9) and has a slope of 3/2. I'm clueless!
Answered by Reiny
Just use your definition of slope, calculate it, then set it equal to 3/2

(9-3)/(x-2) = 3/2
6/(x-2) = 3/2
3x - 6 = 12
3x = 18
x = 6

What do I do to from line 2 to line 3? How did you get 3x- 6=12?

line 2 to 3?

multiply line 2, each side by 2(x-2)
Answered by J.J.
Can you break it down, line by line?not following
Answered by bobpursley
2(x-2)*6/(x-2)=2(x-2)*3/2

12=3x-6
