Direct Proportion means that as one increases, the other also increases.Inverse proportion is the reciprocal of direct proportion. If something is in the direct proportion of 1:3, then the inversion proportion is 3:1.OrIndirect Proportion means that as one increases the other decreases, or one is directly proportional to 1 divided by the other. Example: Pressure is indirectly proportional to volume, or Pressure is directly proportional to 1/Volume.
If the variables x and y are in direct proportion then the graph of y against x is a straight line through the origin. If the variables x and y are in inverse proportion then the graph of y against x is a rectangular hyperbola. Alternatively, the graph of y against 1/x (or 1/y against x) is a straight line through the origin.

Two sets of points are needed to determine the slope of a line
The slope of a line perpendicular to one with slope m is -1/m. So for a line with slope 1/7, any line perpendicular to it will have: slope = -1 / (1/7) = -7

A direct proportion. That is, if one value goes up, so does the other. You can think of it as: unit 1/unit 2 = unit 1/unit 2
1. Direct Proportion As one value increases, so does the other. 2. Indirect Proportion As one value increases, the other decreases. 3. Partitive Proportion A proportion describing the total amount being distributed into two or more unequal parts. Miwa D. Oguro

The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line.

When quantities are related this way we say that they are in direct proportion.

Two variables are proportional to one another if there is a simple relationship, of the following form:The variables X and Y are indirect proportion if Y = c*Xandinverse proportion if Y = d/X or, equivalently, X*Y = dfor some non-zero constants c and d, called the constants of proportionality.Note that if Y is inversely proportional to X, then Y is directly proportional to the variable 1/XThe graph of a direct proportion is a straight line through the origin, with slope = constant of proportionality.
1" per 4' minimum.
A percentage means "out of 100", but it is not unit-specific. This means that 1 percent is the same as 1/100 centimetres, 1/100 inches, 1/100 litres, 1/100 years etc... It is a proportion, not a measurement as such. To clarify, the slope is 1/100 inches. (i.e per every 100 inches you go forwards, you go down 1 inch).
M (slope) = (Y2 - Y1) / (X2 - X1) You need two points on a graph to make it a line. If point A is at (0,0) and point B is at (1, 1) then your slope would be M = (1 - 0) / (1 - 0) = 1 / 1 = 1
