Answer:

y intercept at #y=4#
x intercept at #x=1#

Explanation:

This is an equation of a straight line #y=mx+c#

#color(blue)("Determine the x intercept")#

The graph crosses the x axis at y=0

#color(brown)(y+4x=4)color(blue)(->0+4x=4)#

Thus #color(green)(x_("intercept")=1)#
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(blue)("Determine the y intercept")#

The graph crosses the y axis at x=0

#color(brown)(y+4x=4)color(blue)(->y+4(0)=4)#

Thus #color(green)(y_("intercept")=4)#
