Y = -2/3x + 7.....the slope here is -2/3. A perpendicular line will have a negative reciprocal slope. All tht means is take the original slope, flip it, and change the sign. So we take -2/3....flip it making it -3/2.....change the sign making it 3/2. So ur perpendicular line will have a slope of 3/2.
y = mx + b slope(m) = 3/2 (-5,6)....x = -5 and y = 6 now sub and find b, the y int 6 = 3/2(-5) + b 6 = -15/2 + b 6 + 15/2 = b 12/2 + 15/2 = b 27/2 = b so ur perpendicular equation is : y = 3/2x + 27/2 <==
You are trying to figure out 1/6 of her weight. Since her weight is 19 pounds, you would put it over one to create a fraction and times is by 1/6 which would give you 19/6.
