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
