Answer:
Step-by-step explanation:
The slope of the given line is 1/3.
The perpendiculars all have the negative reciprocal slope, -3.
<span>A. y + 2 = -3(x-4)
Yes, slope -3.
B. y - 5 = 3(x+11)
No, slope 3.
C. y = -3x - 5/3
Yes, slope -3.
D. y = 1/3 x - 2
No, that's slope 1/3.
E. 3x + y = 7
</span>
That's
y = -3x + 7
Another slope -3, Yes.
Answer:
X = (P^2 - 9) ^ 1/2
Step-by-step explanation:
P^2 = (4 - 1)^2+ (0 -X)^1/2
The last one are like terms because they can combine.
