Is anyone here a whiz at math?

Question

I need help on slopes, I'm completely lost. Any help will be greatly appreciated. Thanks

Answer 1

Slope is rise over run or delta y / delta x .

A flat line parallel to the x axis has a slope of zero, i.e. y = 1 , for example.

Negative slopes, i.e. y = -x , go from the upper left to the lower right.

Positive slopes, i.e. y = x, go from the lower left to the upper right.

Answer 2

The slope or the gradient is commonly used to describe the measurement of the steepness, incline, or grade of a straight line. A higher slope value indicates a steeper incline. The slope is defined as the ratio of the "rise" divided by the "run" between two points on a line, or in other words, the ratio of the altitude change to the horizontal distance between any two points on the line.

Using calculus, one can calculate the slope of the tangent to a curve at a point.

The concept of slope, and much of this article, applies directly to grades or gradients in geography and civil engineering.

Answer 3

Slopes is a fairly simple concept actually. Slope is defined as rise over run. What that means is, that from one point on the line, how far up or down (rise) and how far left or right, do you need to go in order to come to another point on the line. When you go down the, the value for "rise" becomes negative. When going up it is positive. When you go left the "run" value becomes negative, and therefore when you go right it becomes positive.

ex: if your slope is 2, that means that you need to go up 2, and right 1, since 2 can also be written as 2/1. For a slope of 2 you also have the option of going down and left the specified values.

On the other hand if it was -2, you would either go left and up, or you go right and down.

Answer 4

Slope is rise over run and has the following equation:

m = (y2-y1)/(x2-x1)

So the change in y, (y2-y1) is the rise, and the change in x, (x2-x1) is run. The slope is just the ratio of "rise" divided by "run."

If you know two points on a graph, you can insert them into the equation to find the slope. The slope measures the steepness between those two points.

If the slope is greater than 1, then it is steep. If it's between one and zero, then it's shallow. If the slope is negative, then the linear equation is not increasing, but decreasing.
