Plot the intercept points: #(0,1)# and #(4,0)#,
then draw a line through those points.

Explanation:

The y-intercept is the value of #y# when #x=0#
For #x=4y=4# this means that the y-intercept is #1#,
giving the intercept point #(x,y)=(0,1)#.

Similarly, the x-intercept is the value of #x# when #y=0#
For #x=4y=4# this means that the x-intercept is #4#,
giving the intercept point #(x,y)=(4,0)#.

Plotting these two points and drawing a line through them gives:
