I think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). Because if you replace x by -4 your are supposed to find y=-3 which is not the case her. If you replace x by -4 you find =-15.
I assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how I found that out I can tell you).
In this equation if I replace x by -4 I find y=-3 and if I replace x by 12, I find y=1 so the line representing this equation is passing through those 2 points.
Then the standard form of the equation is finding an expression of y in function of x
y-1=1/4*(x-12)
y=x/4-3+1
y=x/4-2
Hope that helps.
Do you confirm there was a mistake in the question?
