How to Use the Formula and Calculate Slope. The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.

One way to express slope is as a percentage. To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run.

This is the slope of the line (usually called m). If you need to find the equation of the line simply input all of our knowns into the slope/line formula: y-y1=m(x-x1). For the above example that's y-1=1(x-2). Then simplify and you've got y=x-1.

To calculate the slope of a curve, you need to calculate the derivative of the curve's function. The derivative is the equation of the slope of the line tangent to the point on the curve whose slope you want to calculate. It is the limit of the curve's equation as it approaches the indicated point.

x = how far along. m = Slope or Gradient (how steep the line is) b = value of y when x=0.

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: .

If you think about the slope formula, y = mx + b, if m = 0, then y = 0x+b, and if you multiply anything by 0, it disappears, so zero slope gives y = b. If it is x= #, it is a vertical line through whatever value o x you have.

And the distance is found by using the distance formula. To find the slope, find the difference between the two y values and divide it by the difference between the two x values. The midpoint is obtained by taking the average of the two x values and the average of the two y values.
