Question

Which line is parallel to the line that passes through the points (4, 9), (11, 9)?

x = 4

y = 3

y = x + 4

y = ­x -­ 3

Answer 1

a line parallel to this line would be y=3

Explanation:

parallel lines have the same slope, but different y-intercepts.

the slope of the line that passes through (4, 9) and (11, 9) is 0.

the equation is y = 9.

and that is identical to y = 3, because they both do not have a slope; they both form straight horizontal lines across the graph.
