Answer:
2x - y - 5 = 0
Step-by-step explanation:
As that line is parallel to 2x - y = 4, they must have same slope.
Slope y = mx + c is m, compare that line, slope of 2x - y = 4 is 2.
So the slope of that line is also 2.
Equation is :
=> y - (-1) = 2(x - 2)
=> y + 1 = 2x - 4
=> 2x - y - 5 = 0 or 2x - y = 5
