Write and equation of the line that contains the given point and has the given slope. (-1,-10) slope=-2 the tickets to a concerts cost $12.50 for lowers lever and 6.75 for the upper level. a total of 148,000 tickets were sold for total amount of $136,125. how many lower levels tickets were sold?

Point-slope form is

so using the information given..

simplified


subtract 10 from both sides will put your equation in slope-intercept form


for the second problem, you need to solve a system of equations.
if x stands for lower level tickets and y stands for upper level tickets, you would set up your system:
