How to combine ezplot and scattered values into one plot?

Hi

I am trying to make a manual linear regression line to fit my measured values. The measured values are plotted with the scatter function and my linear regression line is a symbolic equation. I want my regression line to be plotted together with my measured values. My code:

[k,m,sig] = linearRegression(RSSImean, GPSDistance, valLength)
syms x

figure(1)
for a = 1:(valLength)
    scatter(DistanceLog(a), RSSImean(a), 40, 'filled');
    hold on  

end
hold on  
ezplot(k*'x' + m,[DistanceLog(1),DistanceLog(valLength)])

Anyone who knows what I am doing wrong and how it can be solved?

Best regards

Anyone?
