Method below

Explanation:

First, we find the #y#-intercept by substituting #x=0#:
#y=-1/4(0)-5#
#y=-5#, so the y intercept is #(0,-5)#

Then we find the #x#-intercept by substituting #y=0#:
#0=-1/4x-5#
#1/4x=-5#
#x=-20#, so the x intercept is #(-20,0)#

Now what we know two points, we just plot them on the graph and draw a line connecting them and extending past them

graph{y=-1/4x-5 [-31.6, 27.07, -13.28, 16.06]}
