Display Equation on plot

Hello, I am using the lm to fit a linear model to data, I was wondering if there is a way to display the equation on a plot using the extracted lm coefficients? I am using the plot() function to create the plot/.png. Example: lm_mod <- lm(data1~data2) intercept = 48.54 slope = 0.4856 I want to display equation on a plot as y=0.4856x+48.54
mtext(bquote( y == .(slope) * x + .(intercept)), side=1, line=4) will put it in the bottom margin. Use text() with appropriate coordinates to put it in the plot area instead. Duncan Murdoch
Any thoughts or suggestions are appreciated. Thanks, Doug
