Question

Find the vertical and horizontal lines through the point (-1,5). Choose the two correct answers. 1. Horizontal:y-5 2. Vertical: x5 3. Vertical y 5 4. Horizontal: 5 5. Horizontal: x1 6. Horizontaly. 1 7. Vertical-.1 m 8. Vertical y. 1

Answer 1

vertical is x = - 1 , horizontal is y = 5

Explanation:

the equation of a vertical line is

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (- 1, 5 ) with x- coordinate - 1 , then

x = - 1 ← equation of vertical line

the equation of a horizontal line is

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 1, 5 ) with y- coordinate 5 , then

y = 5 ← equation of horizontal line
