-14,-54

Answer 1

the correct answer is D

Answer 2

you don't see any y values that are the same, so you have to write the equations first
equation 1: the slope is m=(14-2)/(3-0)=4, and the y intercept is 2 (you can tell from the point (0,2)) so the equation is: y=4x+2

equation 2:
your last pair of x and y are not correct. they must be 3, -3 instead, not 3, 3
the slope is m=[(-3-(-12)]/(3-0)=3, and the y intercept is -12, so the equation is y=3x-12

solve the system of equation: y=4x+2 and y=3x-12
4x+2=3x-12
x=-14
y=3x-12=3*(-14)-12=-54
so the answer is (-14, -54)
