WebSep 15, 2014 · use pure integer arithmetic. In the case of integer arithmetic, you can obtain the rounding effect easily by computing Y0 + (T.Dy + D/2) \ D instead of Y0 + (T.Dy \ D). Indeed, as you divide by D, this is equivalent to Y0 + T.dy + 1/2. Division is a slow operation. WebMar 1, 2015 · To find the y-intercept (b), you need to set x to one of the x values and y to one if the y values and solve: y=mx+b b=y-mx. The function could look like this: m=getSlope (x1,y1,x2,y2) b=y1-m*x1 return b. The coordinates of the point would be (0,b), so you can return that instead if you want. Share.

WebJul 17, 2024 · If slope is the slope of AB, then the slope of CD is -1/slope. This is equal to vertical change over horizontal change: dy/dx = -1/slope. This gives that dx = -slope*dx. And by Pythagorean Theorem, you have 3**2 = dy**2+dx**2. Substitute for dx, and you get 3**2 = (-slope*dy)**2+dy**2 3**2 = (slope**2 + 1)*dy**2 dy**2 = 3**2/ (slope**2+1) WebSep 6, 2024 · Let us use the concept of least squares regression to find the line of best fit for the above data.
