So first find the gradient. Which is 5- -3 over 3- -5 so it’s 8 over 8 which is one. Then use the formula y - y1 = m(x-x1)
So y- -3 = 1(x- -5)
So y + 3 = x + 5
Then y = x + 2
So the intercept is 2

To find your slope, you have to use the formula.

m = y₂ - y₁ / x₂ - x₁
For these two points:
m = 5 - (-3) / -3 - (-5) = 8 / 2 = 4

So that's y = 4x + b

I don't remember the y intercept method, but it's 17. Just used a calc.

So therefore the slope intercept equation would be y = 4x + 17
