hey does anyone know how to contour a line, 2x+4y+2. I know for an equation of a circle you put the equation equals to k . the radius is square root of k . what you put as the radius and centre here?
thanks for help
Put the line equal to k. i.e and plot the rest of your lines relative to tha one.
To plot, let you k equal different numbers. You will get an infinite number of parallel lines. Plot the one with k=0 (x=0,y=2, y=0,x=1)
As it is the equation of a line, you don't have a center or a radius.
