You can use this equation to write an equation if you know the slope and the y-intercept. Slope m change in y change in x y y 1 x x 1. Find the slope of the following straight lines i 5y 3 0.
So the x-intercept is - y-interceptslope.
If the given curve is yf x y f x we evaluate. The slope of a linear equation can be found with the formula. The equation point slope calculator will find an equation in either slope intercept form or point slope form when given a point and a slope. To find the gradient of other polynomials you will need to differentiate the function with respect to x.
