Question

Witch is the equation of the given line?x = -3x = 3y = -3 y = -3x

Answer 1

y = - 3

Explanation:

the line is horizontal and parallel to the x- axis with equation

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

the line passes through (- 4, - 3 ) and (2, - 3 ) both with y- coordinate - 3 , so

y = - 3 ← equation of line

Answer 2

y=-3

1) Since the graph shows us a horizontal line, where any value of x corresponds to y=-3

(2, -3), (3,-3) etc..

2) Then we have a constant function. y=-3
