HI, im new to matlab and was wondering how would you input a command to help me solve an unknown constant in an equation.
I have a bunch of x,y points,The equation would be x= a*y+b

You say "The equation would be x= a*y+b" and this is the opposite to the way people usually do things, but it can be done. Just reverse x and y when you call polyfit(). Try this:
coefficients = polyfit(y, x, 1); % x as a function of y - note NOT the usual way people do things!
a = coefficients(1)
b = coefficients(2)
