Mary has a budget of $40 per month to spend on movies. She made a table showing the total amount of movie money she will have left after seeing the given number of movies.

Which equation, in standard form, represents the relationship between the number of movies, x, and the amount of movie money Mary will have left, y?

11x - y = 40

11x + y = 40

x + 11y = 40

x - 11y = 40

What is the equation in point slope form of the line that passes through the point ( 2 , 6 )

and has a slope of 5

y + 6 = 5 ( x + 2 )

y - 2 = 5 ( x - 6)

y - 6 = 5 ( x -2)

y + 2 = 5 ( x + 6)
