Answer:

Slope: #(-2)#
y-intercept: #4#
Starting with the y-intercept at #(0,4)# for each unit of #x# (to the right) the line drops down #2# units vertically.

Explanation:

The general slope-intercept form is
#color(white)("XXX")y = color(red)(m)x+color(blue)(b)#
where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept.

#y=color(red)(-2)x+color(blue)(4)# is in the slope-intercept form
