Question 4(b)
I just need to know how to find a gradient from graph
Can some one tell me by editing this picture

Vertical over horizontal

First draw a vertical line from n to 3 since thats were the line stopped and then draw a horizontal line from n on x axis to 3, And this will form a triangle, you need to draw it btw for the marks.

Then vertical/horizontal, in other words, y axis/x axis = thats the gradient

 

[ChrisChin]

gradient of graph = ratio of vertical side to horizontal side = y/x

Use dotted lines for the sides of the triangle.

The larger your triangle is, the more accurate your gradient is.

Try to use a triangle with a whole number for the length of horizontal side -- it's easier to calculate.

Normally we draw the triangle with the hypotenuse on top of the horizontal side.

Mark the right angle.

One more thing -- you can extend your graph if you can get values that are easier to calculate that way. I extended your graph a little.
