The variable z varies jointly with the product of x and y, z = 6, y = 3 and x = 4. Find an equation that relates the variables.

Areal estate agent earns $32,000 a year plus $1,000 for each apartment he sells. write an equation that shows the relationship between the number of apartments abe sells, n, and the total amount he earns in a year, e. what is the total amount abe would earn from selling 10 apartments in one year

I’m stuck on this equation, anyone got the answer?

Rewrite the point-slope equation in slope-intercept form: y - 3 = 2(x + 4)
