If y varies directly as x, and y is 12 when x is 1.2, what is the constant of variation for this relation?
2 answers:
If you multiply 12 by 0.1, you get 1.2. To write this as a function you would say y is x multiplied by 0.1.
y=0.1x
Answer:
B. 10
Step-by-step explanation:
y = k x
12 = k 1.2
k = 12/1.2
k = 10

parallel means same slope. m = 2
y - y₁ = m(x - x₁)
y - (-11)= 2(x - (-3))
y + 11 = 2(x + 3)
y + 11 = 2x + 6
<u> -11 </u> <u> -11 </u>
y = 2x - 5
