Question

What is the slope of the line passing through `(2,5); (0,0)`?

Answer 1

The gradient / slope is `2.5`

Explanation:

To find the gradient / slope of a line from two points, we need to find the difference in `y` and the difference in `x`. To do this, we take the first set of coordinates away from the first (think of it as your finishing point take away your starting point to find the difference).

`"Difference in "x = 0 - 2 = -2`
`"Difference in " y = 0-5 = -5`

Then to find the gradient we divide the difference in `y` by the difference in `x`.

`(-5) / -2 = 2.5`

So the gradient is `2.5`.

Hope this helps; let me know if I can do anything else:)
