Question

The straight line 3x - y + 5 = 0 intersects y-axis at

Answer 1

It intersects y axis at 5 .
x= 0
3(0) - y + 5=0
-y = -5
y =5

Answer 2

$\blue{\huge{\boxed{\star\: Solution \: \star}}}$

=>It intersects at y axis so x=0

$\green{put \: value \: of \: x \: in \: equation}$


===>3(0)-y+5=0

===>0- y+5= 0

===>-y=-5

===>y=5

$\boxed{so \: intersection \: points \: are \: (0 \: and \: 5)}$
