Ok, first we write it as an equation.
12+ 9n = 57.
Then, subtract 12 from each side.
12 - 12 + 9n = 57 - 12.
9n = 45.
Then, divide each side by 9.
n = 45 divided by 9.
n = 5.
Hope it helps! :)

I figured out how to do it.
2-0=2
7-3=4
4/2=2 therefore the gradient is 2.
Now we need the y intercept which is already given (the y intercept is when x=0) when x equals 0 x=3 so the equation of the line is:
y=2x+3

Hope this helps :)
