Which of the following expressions is equivalent to [2x + 3(x + y)]- [a(x + y) - 2y]?
A) (1 -a)(x + y)
B) (5-a)(x + y)
C) 2x - 2y + (3 - a)(x + y)^2
D) 2x + 2y + (3 - a)(x + y)^2

step-by-step explanation:

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 .

do you confirm there was a mistake in the question?

won't that be plagrisim thought?
