I'm so stuck

The gradient of a curve at a point is equal to the slope of the tangent to the curve at that point.
So, find the slope of the purple line. You have one point (3, 2), so you need another. Try (4, 18/5), for example.

sorry hadnt seen the message

what do you mean by (4,18/5) ?

[gloomy wagon]

A possible choice for the second point of the tangent line so you can find its slope.

[true blade]

as in a fraction ? so like 4,3.6 ?

[gloomy wagon]

Yes.

I prefer to use ordinary fractions when possible.

[true blade]

thats fine

[true blade]

so
2-3.6 / 3-4 ?

[gloomy wagon]

Yes. Don't forget to use brackets when you type it like that, though: (2 - 3.6)/(3 - 4).

[true blade]

so 1.6 is the answer?

[gloomy wagon]

Yes.

thank you !
