Question 117314: Using graph paper, graph each question and plot the given ordered pair. Then construct a perpendicular segment and find the distance from the point to the line.
22. y = 3, (4, -1)
What I'm wondering is what y = 3 meant. I thought perhaps it meant that on the graph, the first ordered pair would be (0, 3). I looked through the section, but I can't find anything that would explain this, nor any sample problems like this.
