Answer:

#y = color(red)((-2))x+color(blue)(0)# with a slope of #color(red)((-2))# and a y-intercept of #color(blue)(0)#

Explanation:

The general slope-intercept form is:
#color(white)("XXXX")##y = mx +b#

#4x+2y= 0# can be converted into this form fairly simply:

Subtract #4x# from both sides
#color(white)("XXXX")##2y = -4x#

Divide both sides by 2
#color(white)("XXXX")##y = (-2)x#

To be explicit in our slope-intercept form we still need to specify "#b#"
#color(white)("XXXX")##y = (-2)x+0#
