$y=-2x+1$

Slope $=-2$
Y intercept $=1$

To find the slope and y-int, put it into slope-intercept form by isolating y.

$8x+4y=4$

Subtract $8x$ from each side:
$4y=-8x+4$

Divide each side by $4$ :
$y=-2x+1$

Slope $=-2$
Y intercept $=1$

Given 8x +4y= 48x +4y= 4, how do you identify the slope and y-intercept?
