What it is inverse and direct proportion?
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.
How do you determine direct and inverse proportion on graphs?
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.

What is the slope of the equation through points -1-4?
Two sets of points are needed to determine the slope of a line
Given a line with a slope of 1 7 what is the slope of any line that lies perpendicular to it?
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

What is direct variation?
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
Kinds of proportion?
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

If one slope is -1 what is the slope of the perpendicular slope?
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. 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.
When a graph of 1 quantity vs another results in a straight line the quantity are?
When quantities are related this way we say that they are in direct proportion.
What is proportional relationship in math terms?
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.

What is 1 percent slope in inches?
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).
How much slope does flat roof need?
1" per 4' minimum.
Is x over y the formula for slope of a straight line?
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
