First, plot the y-intercept which is 150. So, plot the point (0,150).
Then, just input values of x into the equation.
Use the value of x you input and y value you got after solving into (x,y) and plot the point.
First you need to figure out the cost of the skateboard after the discount but before the sales tax. By doing 100%-12% you figure out how much of the original cost you are paying 88%. Then you multiply 79.99(original cost) and 88%(how much you pay) which gets you 70.39. Then you figure out the sales tax by multiplying 70.39 by 6.75% which gives you 4.75(the sales tax). And the last thing you need to do is add the cost before tax(70.39) and the tax(4.75).
The skateboard costs $75.14
That would be 222,111 answer
