Answer:
1. A.
2. B
3. A
4. C
5. A
Step-by-step explanation:
1. (5-2)² + (2-(-2))² = distance
sqrt(34) = distance
2. (4-(-1))/(5-2) = slope
5/3 = slope
3. (5+2/2, 4+-1/2) = midpoint
(7/2, 3/2)
4. Just turn the y-axis into negative. So, (x, -y)
5. Reorganize and simplify the whole equation, so that we are left with the y variable in either one of the sides.
2x -7y + 9 = 0
2x - 7y = -9
-7y = -2x -9
y = 2/7x + 9/7
SIF: y =mx + b
Thus, m = 2/7
