Answer:

x-intercept is 2
y-intercept is -4

Explanation:

the x-intercept is the value of #x# where the line of the equation crosses the x-axis; on the x-axis, #y=0#
so substituting #y=0# into #2x-y = 4#
gives
#2x-0=4# or #x=2#

Similarly, the y-intercept is the value of #y# where the line of the equation crosses the y-axis, #x=0#
so substituting #x=0# into #2x-y=4#
gives
#2(0) - y = 4# or #y=-4#
