Answer:

y = (3/4)x + 2

Explanation:

Now we have to write,

→ The equation in slope-intercept form.

The equation is,

→ -3x + 4y = 8

The slope-intercept form is,

→ y = mx + b

Let's rewrite the given equation,

→ -3x + 4y = 8

→ 4y = 8 + 3x

→ 4y = 3x + 8

→ y = (3x + 8)/4

→ y = (3x/4) + (8/4)

→ [ y = (3/4)x + 2 ]

Hence, the answer is y = (3/4)x + 2.

Answer:


\large\boxed{ \tt y=(3)/(4)x+2}

Explanation:


\textsf{We are asked to convert the given equation from standard form to slope-intercept form.}


\textsf{Standard form is a more complex form of a linear equation.}


\textsf{Let's review important information necessary.}


\large\underline{\textsf{Standard Form;}}


\tt Ax+By=C


\textsf{For this equation, A, B, and C are integers.}


\textsf{C is the y-intercept.}


\textsf{A is the slope.}


\textsf{B represents how many times the whole equation \underline{was} multiplied by.}


\underline{\textsf{A more simplified equation;}}


\tt x + y = c


\textsf{We need to change this equation into slope-intercept form.}


\large\underline{\textsf{Slope-Intercept Form;}}


\tt y = mx+b


\textsf{Note that this equation \underline{isn't} multiplied.}


\textsf{M represents the slope.}


\textsf{B represents the y-intercept.}


\textsf{We should change where the y is, and divide the equation by how much B is.}


\large\underline{\textsf{To Start;}}


\tt-3x+4y=8


\textsf{The y-intercept is 8.}


\textsf{The slope is -3.}


\textsf{The equation is multiplied by 4, so we should divide by 4.}


\large\underline{\textsf{Divide by 4;}}


\tt (-3x+4y)/(4) =(8)/(4)


\tt -(3)/(4)x+y=2


\textsf{Now, for slope-intercept form, y has to \underline{equal} the slope and the y-intercept added together.}


\textsf{Modify the equation where y is the result by adding the slope to both sides.}


\large\underline{\textsf{Change into Slope-Intercept Form;}}


\tt -(3)/(4)x+y=2


\tt -(3)/(4)x + (3)/(4)x+y=2 + (3)/(4) x


\underline{\textsf{Switch around the slope and the y-intercept;}}


\large\boxed{ \tt y=(3)/(4)x+2}
