Gradient is vertical rise / horizontal travel.
If its derived from a mathematical expression, use differential calculus.
If its a data driven ( hand drawn ) line, use best approximation tangent at point required.
Find the value of the trend line when x = 0
i think you do Vertical/horizontal
divide by the gradient
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
Yes beccause: (y1-y2)/(x1-x2) = gradient

basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.

The gradient of a line is the same as the slope of a line. It will tell someone measuring the line how straight the line is.
The higher the gradient, the more steeper the line will be.
Select two values of x: (x1 and x2) within the domain. Solve the equation of the line to find the corresponding values for y: (y1 and y2). Then the gradient = (y1 - y2) / (x1 - x2)
The gradient of a straight line cannot be defined- it's infinity.
