Find the gradient of the line joining (3,7) and (6,9).Hence, find the acute angle it makes with the positive x- axis.

Ok, ok, you have now asked 4 questions without giving me any idea where your difficulties lie, or what effort you have made to solve these problems.
We do not do a student's homework here.

e.g. Surely you know how to find the slope or "gradient" between two given points.
You should also know that tanθ = slope, where θ is the angle that the line makes with the x-axis

Sure I know how to find the gradient but I don't know how to find the acute angle in a case like this
