What is the slope of the line with an equation of 5x - 3y = -12

Hoochie [10]

Answer: $m=\frac{5}{3} =1.67$

Step-by-step explanation:

Original equation: $5x-3y=-12$
Subtract 5x from both sides of the equation: $-3y=-5x-12$
Divide both sides of the equation by -1: $3y=5x+12$
Divide both sides of the equation by 3 to get y on the left, leaving the equation in $y=mx+b$ form: $y=\frac{5}{3}x+4$
Evaluate. Slope is equal to m in this form, so the slope is $m=\frac{5}{3}$ .

Hope this helps!

Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation. Y=4.5 when x = 3

Nookie1986 [14]

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=4.5\\
x=3
\end{cases}\implies 4.5=\cfrac{k}{3}\implies 4.5(3)=k
\\\\\\
13.5=k\qquad therefore\qquad \boxed{y=\cfrac{13.5}{x}}$
