Question

the angle between the graph of the equation x+y=0 and y= 0 can be​

Answer 1

Answer:

the angke between is 45 degreee

Answer 2

We are given the equations

$x+y=0$ ------- 1

$y=0$ ----------- 2

Angle of 1 can be calculated as follows :-

$y=mx+c$

$y=-x$

$m_1=-1$

Tan α = -1 ⇔ α = - 45°

Angle of 2 can be calculated as follows :-

$y=0$    ( this line implies that the ordinates of points on this line is 0)

m = 0

Tan β = 0 ⇔ β = 0°

∴ Angle between  $x+y=0$  and  $y=0$ is 0-(-45)° = 45°
