Perpendicular to a line with a slope of -3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So we have a slope of -3 (or -3/1).....flip it, making it -1/3....change the sign, making it 1/3. So our perpendicular line will have a slope of 1/3.
y = mx + b
slope(m) = 1/3
(6,1)....x = 6 and y = 1
now we sub into the formula and find b, the y int
1 = 1/3(6) + b
1 = 2 + b
1 - 2 = b
-1 = b
so ur perpendicular equation is : y = 1/3x - 1 <==
Answer:B
Step-by-step explanation:
Given
Every student secure same average score
Standard deviation is denoted by \sigma
Consistency is criteria of acceptance then Student should be selected the standard deviation is least for student B.
Standard deviation tells how a data varies from mean Position .
More Deviation from mean indicates less consistency .
Answer:
-x-15
Step-by-step explanation:
x-2x-15
1x-2x-15 (if a term doesn't have a coefficient then the coefficient is 1)
(1-2)x-15 (collect like terms by subtracting their coefficients)
-1x-15
-x-15 (when the term has a coefficient of -1, the number doesn't have to be written but the sign remains)
