y varies inversely with x. If x is 6.4 when y is 1.5, what is k, the constant of inverse variation? Round your answer to the nea
rest hundredth, if necessary.
1 answer:
If y varies inversely with x, then we know that:
y = k/x
We are given x and y, so plug in the numbers and solve for k.
1.5 = k/6.4
k = 1.5*6.4
k = 9.6

We have two points so we can use the sloe formula
m = (y2-y1)/(x2-x1)
= ( 10-10)/(1-4)
= 0/ -3
= 0
