The slope of the given line is m = 8
You can think of m = 8 as m = 8/1. Flip the fraction to get 1/8 and then flip the sign to get -1/8
Answer: -1/8
Note: Multiplying the original slope (8) and the perpendicular slope (-1/8) will lead to the result of -1. This applies to any two perpendicular lines as long as one of the lines isn't vertical.
So if the line is linear we can use slope intercept form to find the equation of the points: y=mx+b
To calculate m, the slope we subtract two of the points (I’ll use the first two):
(-1, 1)
(4, 0)
This equals 0-1/4+1, which simplifies to -1/5
So the slope is -1/5 and we can put that into slope intercept form along with a point to get b, the y-intercept.
So, y=-1/5x+b
Now we substitute x and y with a point.
1=-1/5(-1)+b
1=1/5+b
b=4/5
So the equation is:
y=-1/5x+4/5
I hope this helps!
Answer:
14 bags
Step-by-step explanation:
5 2/3 - 5 4/6
8 1/2 - 8 3/6
9 1/6 - 9 1/6
Add them up
sum= 23 1/3 or 70/3
divide it by 1 3/4
= 14 bags
Answer:
Step-by-step explanation:
For a male student who has a measured pulse rate of 52 beats per minute.
Raw Score, X =52 beats per minute.
Therefore:
Since the usual pulse rates are within 2 standard deviations of the mean, a z-score of -1.49 tells us that the selected student's pulse rate is within the usual pulse rates.
