Answer:
B
Step-by-step explanation:
given x varies inversely with y, the the equation relating them is
x = ← k is the constant of variation
To find k use the condition x = 6 when y = 10, hence
k = xy = 6 × 10 = 60
x = ← equation of variation
When x = 8, then
8 × y = 60 ( divide both sides by 8 )
y = = 7.5 → B

Answer:
y-1= -4(x-(-3))
y minus 1 = negative 4 left-bracket x minus (negative 3) right-bracket
Step-by-step explanation:
The formula for point slope form is written: . Now we fill in our know information. m=-4 (because that is the slope),
=1 (It is the y value in the ordered pair),
= -3 (It is the x value in the ordered pair).
y-1=-4(x- (-3))
