Question

Write the equation for the vertical line that contains point E(–7, 7).

Choose one answer.
a. y = –7
b. y = 7
c. x = 7
d. x = –7

Answer 1

It would be B. y = 7 because it says write the equation for the VERTICAL LINE which is the y axis. Since the points are (-7, 7), it is the same thing as (x, y) the positive 7 is where the y is, so it would be y = 7

Answer 2

x=-7

Explanation:

the equation for the vertical line that contains point E(–7, 7)

General equation of a vertical line is x= some number

The given point is (x,y)

point E (-7,7) where
`x=-7 , y=7`

To get the equation of the vertical line

x= value of x in the given point

`x=-7` is the equation of the vertical line
