Which expression is used to find the slope of a line?

The steepness of a line can be measured as the slope of a line. The letter 'm' is used to denote the slope and it can be expressed as m= (y coordinate of A- y coordinate of B)/ (x coordinate of A- x coordinate of B). A and B are two points on the line.

What is the term for the vertical line on a coordinate plane?

"The" vertical line is wrong; there are lots of vertical lines on a coordinate plane. In the usual x-y coordinate system, such a line has an equation of the form:x = a (for some constant "a"); for example: x = 3


Which method could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoint at 0 0 and 0 15?

Each coordinate of the midpoint of a straight line segment is the arithmetic mean of the coordinates of the endpoints. So the y-coordinate is (0+15)/2 = 7.5
