You can put this solution on YOUR website!
An equation is "linear" if the degree of the independent variable (x in this case) is 1.
Another way to determine if the equation is linear is to graph it and see if you get a straight line. If you do, the equation is linear, if you don't, it isn't!
Your equation is:
3x%2B5+=+2y Solve for y:
y+=+%283%2F2%29x%2B5%2F2 Let's see what the graph of this equation looks like:
