5 \/180 (please note that \/180 is the square root symbol I’m using
= 5 \/4 x \/45
= 5 x 2 \/9 x \/5
= 10 x 3 x \/5
= 30 \/5
I did this a couple of years ago in AS maths and I think this is how it’s done. Hope it’s helpful!

Answer:
x : 1 | 2 | 3. | 4. | 5. | 6. | 7 | 8 |
p(x) : 1 | 2/3 | 2/3 | 1/3 | 2/3 | 1/3 | 1/3 | 0 |
When x=1, 7x+3 = 10.
When x=2, 7x+3 = 17.
When the value of 'x' changes from '1' to '2', the value of 7x+3 changes
from '10' to '17' . . . a distance of '7' .
That's what the ' 7x ' in the equation means, and that's what we mean
when we say that the 'slope' of the equation is '7'. 'y' changes '7' for
every '1' that 'x' changes.
