y=mx+b
m=sloe
b=yint
given
slope=-2
yintercept=8

y=-2x+8
add 2x to both sides
2x+y=8
minus 8 both sides
2x+y-8=0

y= -2x +8 is slope intercept form. To change it to standard form you have to move the x to the left side. Add 2x to both sides. Then move the 8 to the left side so subtract 8 from both sides.
2x + y -8=0
The second one is correct
