If you use distributive property what does r + 3 + 5r + 9 equal?

The answer is 6 + 1 2

In a linear function, there will be no curves or overlaps. Look for regular equations in slope-intercept form, standard form, or point slope form. In an exponential function, there will be curves and no overlaps. Any overlapping would mean it is neither exponential or linear. Look for exponents or curves in your graph. Also since you are given tables for some of these, the ones with any repeating x values are neither exponential or linear. Hope this helps!
