Question

13. Write the equation of a horizontal line that passes through the point (3, -3).

O x = -3
Ox= 3
O y = 3
O y = -3

Answer 1

O y = -3

Explanation:

Equations beginning with 'x=' would form a vertical line, not a horizontal line.

The point (3,-3) would satisfy y = -3.

-3 = -3

O y = -3 should be the correct answer.

Answer 2

O y = -3

Explanation:

The line is horizontal.

x = -3 and x = 3 are vertical lines, so they are incorrect.

The line passes through (3, -3).

(x , y)

Put y as -3.

y = 3

(-3) = 3

Line y = 3 is incorrect.

(-3) = -3

Line y = -3 is correct.
