Write an equation for the line perpendicular to the y-axis through the point (4,-10)

y = - 10

Step-by-step explanation:

A line perpendicular to the y- axis is a horizontal line parallel to the x- axis.

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (4, - 10) with y- coordinate of - 10, thus

y = - 10 ← is the equation of the line

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the answer is 8.64
