We want to get rid of the square root sign somehow, so let's isolate that term.
Now, in order to 'undo' a root sign, we need to do the opposite to it, by squaring the term, but in order for it to remain the same, we need to square 4 as well.
Now, we can isolate the variable:
, and since we can't simplify this further, our final answer becomes:
or

To find the slope(m), you use the slope formula:
And plug in the two points
(x₁ , y₁) = (1, 0)
(x₂ , y₂) = (5, 3)
