A salespersons weekly pay “y” depends on the volume of sales. If the salesperson sells “x” units of goods, then the pay is given by the linear equation y = 6x+120. a. Graph the equation labeling the x-intercept and y-intercept. b) what is the least amount of money that the salesperson will earn? c) . Show using the linear equation above what the salesperson’s weekly pay if 40 units are sold. d) use Desmos to determine the salesperson’s weekly pay if 20 units are sold. e) use Desmos to determine how many units must be sold in order to have a weekly pay of $600.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
