Line has equation of y= x+4 write coordinates of point where line intersects y axis

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
