Answer:
Step-by-step explanation:
Y α 1/x
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.
Answer:
y=1/2x+0.5
Step-by-step explanation:
I'm assuming the y intercept is 0.5
