Find the points at which the line intersects the axes.

This is a linear function, which has the form Y=MX+C, where M is the gradient and C is the Y offset.

Set X=0 Y=C. So that you can find from the answers you have.

Now, set Y=0, and rearrange the equation to give you "M". Substitute the values you already have.

This is stuff we did when we were about 12 in the UK when I was younger.

Alternatively, go away and study the equation of the straight line. Look at the maths I showed you, with the Y=MX+C Play with some numbers into it, say M=0.5, C=1, X=0...5 Repeat for M=1, 2 etc

as y is inversely proportional to x,

so y=m/x + c

In answer to your other question:

Plot it. Y=1/X is NOT linear !

Let Y = 0

0=MX+C

C is known. X, when Y =0 is known. Calculate M
