Answer:
Well the sides have to be even so
2x+4=3x-10
so x would have to be equal to 14
There is a formula to find the slope (m)
(y2 - y1) / (x2 - x1)
So we now have y = mx + b where m is the value you just calculated
The y intercept (b) = y - mx
Plug in the x,y values for one of your points into this formula
