Answer:

y = 1/10x + 9/10

Explanation:

Find slope intercept form: –2x = –20y + 18

slope intercept form: y = mx + b

_______________________________

–2x = –20y + 18

add 20y to both sides:

–2x + 20y = –20y + 18 + 20y

–2x + 20y = 18

add 2x to both sides:

–2x + 20y + 2x = 18 + 2x

20y = 18 + 2x

divide all terms by 20:

20y/20 = 18/20 + 2x/20

y = 9/10 + 1/10x

reorder terms for slope intercept form:

y = 1/10x + 9/10

Answer:


y=(1)/(10)x+(9)/(10)

Explanation:


\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}

Given equation:


-2x=-20y+18

To write the given equation in slope-intercept form, make y the subject.

Add 20y to both sides:


\implies 20y-2x=-20y+18+20y


\implies 20y-2x=18

Add 2x to both sides:


\implies 20y-2x+2x=2x+18


\implies 20y=2x+18

Divide both sides by 20:


\implies (20y)/(20)=(2x+18)/(20)


\implies (20y)/(20)=(2x)/(20)+(18)/(20)


\implies y=(1)/(10)x+(9)/(10)

Therefore, the given equation in slope-intercept form is:


\boxed{y=(1)/(10)x+(9)/(10)}
