Answer:
Step-by-step explanation:
let an equation of this line : y= ax+b ....a : is the slope
1) the acute angle subtend by it and the line 4+y=0 equal to 45 degree
so : a = tan (45°) =1
so : y = x+b
calculate : b this line passes through point A(2,1) : 1= 2+b
b= - 1
conclusion : y = x -1 color : red 4+y =0 color : bleue
