Let us the formula to calculate the slope of the. Use a protractor to measure that angle and then convert the angle to a decimal or a fraction using a trig table. The second diagonal goes from -3-1 to 31 the slope of this diagonal would be change in y divided by change in x which becomes 1 - -1 3 - -3 which becomes 2 6 which becomes 13.
The slope of a line is a non-angular representation of the angle between the line and a horizontal line such as the x-axis.
We will use the formula to calculate the slope of the line passing through the points 38 and -2 10. Distance Formula gives. Add the diagonal products x1y2 x2y3 x3y4 and x4y1 are shown in the dark arrows. This is precisely the Pythagorean Theorem if we make the substitutions.
