Answer:
4(x + 1) and 4(x - (-1))
Step-by-step explanation:
4(-1 + 1) = 4(0) = 0
(4 (-1) + 5) = -4 +5 = -1
4(-1 - 1) = 4(-2) = -8
(5 - 4(-1)) = 5 + 4 = 9
4(-1 - (-1)) = 4(0) = 0
4 (-1 + (-1)) = 4(-2) = 8
To find a perpendicular line, you need to find the negative reciprocal of the slope.
-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.
Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
May I ask if you have a picture of the question or?
