For two points, take the y coordinate of the second one (in some arbitrary order) and subtract the y coordinate of the first one. Its possible they want the answer to be positive, so if its negative multiply by -1.
A bit more context would help though...

What is the difference of the y-values of two points on a line?
The difference in the y-values of two points on a line is equal to the vertical distance between those points. This difference is also known as the "rise" or the "change in y." To calculate the difference in the y-values of two points (y₁, x₁) and (y₂, x₂) on a line, you simply subtract the y-coordinate of one point from the y-coordinate of the other: Difference in y-values = y₂ - y₁ This calculation gives you the vertical distance between the two points on the line.
You can find the rise by the y-coordinate of the left point from the y-coordinate of the right point?
subtracting
What is the name of the x and y in an ordered pair?
The first and second coordinate. X is the first coordinate and y is the second.
Is the line that crosses the y-axis called a y-intercept or a x-intercept?
A line is just a line, but the y-coordinate (the point where the line intersects the y-axis) is termed the y intercept. This point has an x coordinate that is always zero and the y coordinate can be positive, zero, or negative
How can you tell by looking at the coordinate of a point whether the point is on the x-axis or y-axis?
the x coordinate is always before the y coordinate just like in the alphabet

What is a y coordinate?
A y coordinate is when you have a long line (y axis) and you coordinate (put numbers on that line) and you graph them

What is the slope of the line between 2 5 and 4 17?
Slope = (difference in y coordinate) / (difference in x coordinate) = (17 - 5) / (4 - 2) = 12/2 = 6
How do you find the vertical rise?
The rise, or vertical difference, between two points on the coordinate plane is the difference i their y-coordinates.
What is the difference between the abscissa and the ordinate in a graph?
The abscissa is the x or horizontal coordinate. The ordinate is the y or vertical coordinate. I remember them because they are both alphabetical.
What is the y-coordinate in the ordered pair (4 -1)?
The y coordinate is -1 and the x coordinate is 4
what is y-coordinate in rectangular coordinate system?
A point's y coordinate is its vertical position, or how high or low it is.
Is y coordinate always a negative number?
No, the y-coordinate can be positive or negative.
What is the steepness of a line measured by the difference of y divided by the difference of x?
Its called the "slope" of the line, and I think its actually X over Y (X/Y). Where on a coordinate plane, you measure first horizontally and then vertically.
What the coordinate is called?
x-coordinate: abscissa y-coordinate: ordinate
What is the x coordinate for all y-intercepts?
The x coordinate for all y intercepts is 0, just as the y coordinate for all x intercepts is 0.
