7-3=4
4/2=2
The answer is 2
The slope is 3/4. you need to find the change of y over the change of x.
and
so

and you rationalize denominator by multiplying numerator and denominatr by
so that gives--

Your answer is 
All three sides of the triangle are the same so youcan set two of the equations equal to each other and solve for x:
4x-10 = 3x +2
Add 10 to each side:
4x = 3x + 12
Subtract 3x from each side:
x = 12
