Question

finding the gradient in a graph using line of best fit and line of best fit​

Answer 1

Answer:

finding the gradient of a straight line graph

The gradient of a line =

to calculate the gradient of a straight line we choose two points on the line itself.From these two points we calculate: the difference in height ( y - co-ordinate) ÷ the difference in width (x- co- ordinate) . If the answer is positive value then the line is uphill in .direction
