The graph of 2x – 3y = 21 crosses the y-axis at what point? Select one: a. (0, –7) b. (0, 7) c. (–7, 0) d. (7, 0)

i think this one is C also

OpenStudy (chriss):

The point where a line crosses the y axis is the y-intercept. Therefore at that point, x=0. So you can eliminate c and d immediately. The next step is to substitute 0 for x in the given equation and solve for y.

OpenStudy (camerondoherty):

-3y=21

OpenStudy (chriss):

you are correct. nicely done!
