Slope

slope

1. An oblique direction; a line or direction including from a horizontal line or direction; also, sometimes, an inclination, as of one line or surface to another.

2. Any ground whose surface forms an angle with the plane of the horizon. buildings the summit and slope of a hill. (Macaulay) Under the slopes of Pisgah. (Deut. Iv. 49. (rev. Ver))

A slope, considered as descending, is a declivity; considered as ascending, an acclivity.

(Science: geometry) Slope of a plane, the direction of the plane; as, parallel planes have the same slope.

Origin: Formed (like abode fr. Abide) from OE. Slipen. See Slip.

Presenting stats results - need help!!

... done general linear models - do i just need the p value and r^2 in the main text? For the apppendix I've put a table with the following... Model; Slope; SE; DF; r²; p-value; with a row for the whole model, and a row for each variable with the difference in DF, r^2 and pvalue if each variable is ...

gel electrophoresis & assays help please

... kind of assay would be either different time points (qty of product over time) for each sample, and then the activity of your enzyme would be the slope of the time vs qty line (ie qty of product created for a given unit of time). If there is no time involved, what you might have to do is to calculate ...

Re: Calculating Enzymatic Rate

Rise/run is the same thing as slope of a line. You need two x values and two y values. Such as (2,1)(4,2) These are xy coordinates. Rate of change is DeltaY/Delta X or in our example above 1-2/2-4 = -1/2 This number is only meaningful if ...

Enzyme kinetics

Sorry, that should be X -intercept = -1/Km, not y-intercept. And the slope is Km/Vmax not Vmax. Memory didn't serve me very well this time and I was too lazy to derive it from the rate expression-though that's a useful excercise if you've never done it before. ...

Re: Enzyme kinetics

... plot; not at all linear.) If you have a calculator that will do linear regression, enter your values of (1/s,1/v) as your (x,y) pairs. The slope of the regression will be Vm while the y-intercept is -1/Km. You can estimate them graphically if you prefer, but regression is a bit more accurate, ...
