                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!

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

    line 2 to 3?
multiply line 2, each side by 2(x-2)
    
multiply line 2, each side by 2(x-2)

    2(x-2)*6/(x-2)=2(x-2)*3/2
12=3x-6
    
12=3x-6
