<span>Perpendicular lines' slopes are reciprocals of one another. So we know the perpendicular line will have a slope of 1/2. Then we can use our points to find the rest.
8=1/2(1)+b
8=0.5+b
7.5=b
y=2x+b</span>
Answer:
C, D, E
Step-by-step explanation:
You just need to multiply the numbers together. Whichever choice is equal to 24, is your answer
So when you multiply for each one...
A is 36
B is 48
C is 24
D is 24
E is 24
So since C, D, E multiply to 24, they are the correct answers.
Answer:
-i(6/7)√2
Step-by-step explanation:

If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!
(4,12) is the correct answer
