It is based on the slope. Plug in these values to the slope formula to find the slope. The slope of a linear equation can be found with the formula.
If the form of the equation is ymxc then the slope or gradient is just m.
Just type numbers into the boxes below and the calculator will automatically find the slope of two points How to enter numbers. 6x - 2y 10 -2y 10 - 6x y 3x - 5 The slope of this line is 3 so the perpendicular slope will be -13. 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. We use this definition when calculating slope or graphing slope.
