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.
1. m = -5/2
2. b = 15
3. y = -5/2x + 15
The answer you're looking for is f(2x-9)
Answer:12, 84 and 84
Step-by-step explanation:
since we know 3 angles of a triangle = 180 degrees
1 angle = 12 degrees
12 + x + x = 180
12 + 2x = 180
2x= 180 - 12
2x = 168
x = 168/2
x = 84 degrees
