it is called the slope
It is called direct variation.
The numerator of the second ratio and the denominator of the first ratio are called the means, and the numerator of the first ratio and the denominator of the second ratio are called the extremes. The product of the means equals the product of the extremes.

The slope.
It is called the slope of a line.
note: that one and two on the y's ans x's and doesnt mean to the 2nd or 1st powery2-y1_______ x2-x1
ratio between oxygen usage to oxygen uptake is called as Oxygen extraction ratio
The ratio of rise and run in a linear function (which its graph is a nonvertical line) is called the slope of the line. We can calculate the slope of the line by using any two points on the line and always the ratio of changes on their y-coordinates and the changes on x-coordinates (rise and run) is constant (unchanged). The reason is that two points determine a line and its direction, so the line is fixed and extends without end in that direction. Any line intersects the x-axis only at one point (we call it the x-intercept point) by forming an angle α (the inclination angle), where 0˚ ≤ α < 180˚, that is measured from the positive x-axis to the line. There is a theorem that state that the slope of a nonvertical line is the tangent of its inclination: m = tan α if α ≠ 90˚ (if α = 90˚, then the line is vertical and has no slope).
look at the scale of the map
Yes, it is possible. For instance there could be a gear ratio of 3.1:1 or you can have a waist-hip ratio of 0.8:1.
The ratio between current assets to current liability is called "Current Ratio".
It can be measured as the ratio between two points in the image compared to the same two points in the pre-image.
Yes. Calculate the ratio of the difference in y-coordinates and the difference in x-coordinates between pairs of points. If the ratio is the same, the points are collinear. If not, they are not. The only exception is if all the x-coordinates are he same and the ratio is not defined. In this case the points are also collinear - all on a vertical line.
The average slope is the ratio of the change between two points
Equal intervals between points of that scale and a true zero
