OpenStudy (anonymous):

I think it is C

Which is the equation of the given line? A. x = –4 B. y = –4 C. y = –4x D. x = 4

OpenStudy (anonymous):

A?

OpenStudy (mathstudent55):

For the first question, notice that in the graph, all points on the line have a first coordinate of 2. No matter what the y-coordinate is, the x-coordinate is always 2. It's as if y doesn't matter at all. In fact, the equation is simply x = 2 without y even being mentioned. A vertical line has equation x = k, where k is the x-intercept and the x-coordinate of all points on the vertical line.

first one is D.

OpenStudy (anonymous):

B

undeadknight26 (undeadknight26):

this is because it rests on the x axis...

OpenStudy (mathstudent55):

A horizontal line has the same y-coordinate for all points. The equation of a horizontal line is y = k, where k is the y-intercept and the y-coordinates of all points on the line.
