$40/12 = unit rate simplify = 10/3
$10/3 per book
18 * 10/3 = $60 for 18 copies
Answer:
y + 1 = -(x + 10)
Step-by-step explanation:
- Point-Slope Form: y - y1 = m(x - x1)
The given coordinate (-10, -1) are your (x1, y1), so:
All you have to do is substitute the given information into the formula:
- y -(-1) = -1(x -(-10)), which will simplify to y + 1 = -(x + 10)
Remember: Double negatives make a positive so if the given coordinates for (x1, y1) are negatives, they will be added to y or x in point-slope form, not subtracted.
