Answer:

y = -2x +3\\\rule{150}{0.5}\\\text{Slope: -2}\\\text{Y-Intercept: 3}

Step-by-step explanation:

We would have to convert the standard equation into slope-intercept form.

======================================

<h3><u>Converting the equation into Slope-Intercept Form:</u></h3>

<u />8x + 4y = 12\\\rule{150}{0.5}\\8x - 8x + 4y = 12-8x\\\\4y = 12-8x\\\\4y = -8x + 12 \leftarrow \text{I switched the order on the right side.}\\\\\frac{4y=-8x+12}{4}\\\\\boxed{y = -2x + 3}

======================================

<h3><u>Identifying the Slope and Y-Intercept:</u></h3>

<em>General slope-intercept form is: </em>

<em></em>y=mx + b\\\rule{150}{0.5}\\\text{m - Slope}\\\text{b - Y-Intercept}

<u />

In the equation y = -2x + 3,  '-2' would be the slope since it is in 'm's place, and '3' would be the y-intercept since it's in 'b's place.

<em>Therefore:</em>

<em></em>\text{In } y=-2x+3\text{...}\\\rule{150}{0.5}\\\text{Slope: -2}\\\text{Y-Intercept: 3}<em></em>

======================================

<em>Hope this helps!</em>
