Plot Regression Equation Without Data

I have some regression equations that I want to plot, but do not have the data. Is there a way to create create a plot with only regression coefficients and intercept?

That makes sense. I was hoping there was an easier/more straightforward method, such as inputting regression coefficients and the intercept and having a graph pop out.

Thanks!
