Write an equation for the proportional relationship shown in the graph.
Graph: Necklaces Sales
Total Amount Earned (Dollars) (0,0) 12345 Number Sold
DO NOT USE ANY SPACES between variables, constants, equals signs, and operation signs. For example, DO NOT enter y=2x+1. DO ENTER: y=2x+1
Put parentheses around constants that are fractions like this: y=2/3x-1/2
To write your equation, use the variables: n = number of necklaces sold, a = total amount earned on necklaces ($)
The equation in slope-intercept form is:
