Question

The equation of a line is y = 3. Write an equation in slope-intercept form of a line parallel to y = 3 that passes through (0, 6).

A: x = 3
B: x = 6
C: y = 3x
D: y = 6

Answer 1

New line is parallel to y = 3 , so it has a same slope ( m=0 ) and  y-intercept is b = 6.
The equation of the new line is : y = 6
Answer: D)
