What is the slope of the line created by this equation?Round your answer out to two decimal places.3x+5y=7

tia_tia [17]

The given equation is

$3x+5y=7$

Consider the slope-intercept form.

$y=mx+b$

Rewriting the given equation in the slope-intercept form.

$3x+5y=7$

Subtracting 3x from both sides, we get

$3x+5y-3x=7-3x$

Dividing both sides by 5, we get

$\frac{5y}{5}=\frac{7-3x}{5}$ $y=-\frac{3}{5}x+\frac{7}{5}$

$y=-0.6x+1.4$

Compared to the slope-intercept form, we get m=-0.6 and b=1.4.

Hence the slope m= -0.60.

Makovka662 [10]

<span>4y-9=15
Add 9 to both sides.

4y = 24
Divide both sides by 4.

y = 6

The value of y is 6.</span>

$(\stackrel{x_1}{3}~,~\stackrel{y_1}{6})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{18}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{18}-\stackrel{y1}{6}}}{\underset{run} {\underset{x_2}{5}-\underset{x_1}{3}}} \implies \cfrac{ 12 }{ 2 } \implies 6$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{6}=\stackrel{m}{ 6}(x-\stackrel{x_1}{3}) \\\\\\ y-6=6x-18\implies {\Large \begin{array}{llll} y=6x-12 \end{array}}$
