Let the number be x.
8 - x = x -34
2x = 8 + 34
2x = 42
x = 21
Answer: The number is 21.
You rented 12 movies ( 68.88 - 45.00 = 23.88 then divide 23.88 by 1.99 to get 12)
To write an equation in slope intercept form given the slope and a point, plug into point-slope form.
(y - y1) = m(x - x1)
In this equation, m is your slope and (x1, y1) is your point. If you follow this and solve for y, you will get your equation in slope intercept form.
