Find an equation of the y-axis.

Short Answer

Expert verified

Equation of the y-axis:x=0

Step by step solution

01

Step 1. Finding the equation of y-axis 

Slope-intercept form of line: y=mx+b

Taking two points on y-axis: role="math" localid="1646023835734" (0,0),(0,d)

Putting (0,0)we get, 0=m(0)+b

0=0+b

b=0

Equation becomes, y=mx

y=y2-y1x2-x1(x)

y=d-00-0(x)

y=d0(x)

x=(0)(y)d

x=0
