Put the following equation of a line into slope-intercept form, simplifying all fractions.

Inessa [10]

Answer:

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

Step-by-step explanation:

<u>Slope-intercept form:</u> y = mx+ b

m = slope

b = y-intercept

<u>Rearrange the equation:</u>

$-20y=-12x+60$

<u>Divide each side by -20:</u>

$\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}$

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

$y=\frac{3}{5} x-3$ is your simplified, slope-intercept form equation.
