Help would be greatly appreciated!!! This gets really confusing for me.
Write an inverse variation equation. If y varies inversely with x and y=2 when x=4….
a. Find K.
b. Write a general equation.
c. Use your equation to find y when x=8
Draw a chart to show at least 5 ordered pairs that are on the graph. (Hint: don’t pick all positive numbers)
x- y-

Since you know about k, you must surely have grasped the idea that if y varies directly with x, then
y = kx
You know that y=2 when x=4, so
2 = k*4
k=1/2
... the rest should be easy. Just use your fancy new equation.
y = x/2
8/2 = 4, so y=4 when x=8
x: -21 -3.4 0 π 6
y: -21/2 -1.7 0 π/2 3
y = kx
