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.
The slope of the line is -10.5.
What is the rest of the question and you will probably have to multiply
3) four hundred fifteen thousandths
4) three hundredths
5) thirty four hundredths
6) sixteen hundredths
7) three and five thousandths
8) one and nine hundredths
Combine like terms
7n+5=26
So n equals 3
