Question

Name two coordinates that are on the line:
`y = 12`

Name two coordinates that are on the line:
`x = -5`

Write the equation of the line that passes through the point (3, -5) and is perpendicular to the line x = 4.

60 Point offer.

Answer 1

(1, 12)

(420, 12)

Any coordinate with a y value of 12 lies on the line y = 12.

-----

(-5, 69)

(-5, 13)

Any coordinate with an x value of -5 lies on the line x = -5.

-----

Since the equation must be perpendicular to the line x = 4, which is a vertical line, it must also be written in the form x = a.

Since the x coordinate is 3, the equation of the line is simply x = 3.
